How do these concepts apply with AI?

See the solution ADR (Average Daily Rate) ADR (Average Daily Rate) is the metric that shows the average price a guest pays per occupied room night. It is one of the cornerstones of revenue management because it measures, directly, the hotel's ability to sell its rooms at a strong price, leaving aside the rooms that stayed empty. Read definition AEO & GEO for Hotels AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are digital marketing disciplines focused on getting your hotel found and recommended by answer engines and generative AI, such as ChatGPT, Google AI Overviews, Perplexity or Gemini. Unlike classic SEO, which aims to rank blue links, the goal here is to be the answer the AI shows or cites directly to the traveler. Read definition Agentic AI Agentic AI is a type of artificial intelligence that doesn't just answer questions, it acts to complete tasks on its own. An AI agent can plan steps, make decisions, use tools, and connect to other systems to reach a goal, adjusting along the way based on the results it gets. It's the leap from AI that converses to AI that executes. Read definition Airport Hotel Transfer An airport hotel transfer is the transport service that takes the guest from the airport to the property, and back again on departure. It can be run by the hotel itself, arranged with transport companies, or handled by an external partner, ranging from shared shuttles to private chauffeured vehicles depending on the category and guest type. Read definition ALOS (Average Length of Stay) ALOS (Average Length of Stay) measures the average number of nights a guest stays at the hotel per reservation. It's a key indicator for understanding demand behavior and planning operations, since longer stays reduce the costs tied to room turnover, such as deep cleaning, managing check-ins and check-outs, or paying commissions on new bookings. Read definition Aparthotel An aparthotel (also written apart-hotel or serviced apartment) is a type of accommodation that blends the comfort of an apartment with the services of a hotel. Each unit works as a self-contained apartment, with a kitchen or kitchenette, living area and often a washer, while the guest still has access to hotel-style services such as a front desk, periodic housekeeping and, depending on the category, a restaurant, gym or pool. Read definition Astrotourism (Dark Sky) Astrotourism is travel driven by observing the night sky: stars, constellations, meteor showers, auroras, or eclipses. It is also called dark-sky tourism because it depends on destinations with low light pollution, typically rural, desert, or mountain areas. Read definition Banquet Event Order (BEO) A Banquet Event Order (BEO) is the master document that details all the logistics of an event or banquet within a hotel. It spells out point by point what needs to happen, when, where, and with which resources: timing, room setup, menus, guest counts, audiovisual needs, assigned staff, and billing terms. It is the operational contract that connects what was agreed with the client to what each department must execute. Read definition Bleisure Travel Bleisure travel is the trend of blending a business trip with leisure time. The word merges business and leisure, and it describes the professional who tacks extra nights onto a work trip to explore the destination, relax, or bring along a partner or family. Read definition Booking Abandonment Booking abandonment happens when a potential guest starts the reservation process on your booking engine or another sales channel but leaves without completing payment. It is the hotel equivalent of the abandoned cart in e-commerce: the intent to book was there, but something interrupted the conversion before it was confirmed. Read definition Boutique Hotel A boutique hotel is a small-scale property, usually between 10 and 100 rooms, that stands out for its thoughtful design, distinctive identity and highly personalized experience. Unlike large standardized chains, every boutique hotel has character: a theme, an architectural aesthetic or a connection to its local surroundings that makes it one of a kind. Read definition Channel Manager A channel manager is a tool that connects and synchronizes, in real time, your hotel's availability, rates, and restrictions across every sales channel: OTAs, booking engine, GDS, and agencies. When a room sells on one channel, inventory updates automatically across all the others. Read definition ChatGPT for Hotels ChatGPT for hotels refers to the practical use of ChatGPT and other large language models (LLMs) to support a hotel's daily work. These models understand and generate natural language, which means they can be applied to guest service, content writing, translation, review analysis, drafting replies to comments and many other tasks that used to take hours of manual work. Read definition Contactless Hotel A contactless hotel lets guests complete most of their stay without physical contact or paperwork: digital check-in and check-out, mobile keys, contactless payments, requests through messaging and information access via their phone. The goal is to reduce friction and unnecessary touchpoints, not to remove the human touch where it adds value. Read definition Conversational AI Conversational AI is the set of artificial intelligence technologies that let a machine understand human language and hold a natural conversation, whether by text or voice. It combines natural language processing (NLP), intent detection, context management and, in its modern forms, large language models (LLMs) that generate coherent, personalized responses. Read definition CSAT (Customer Satisfaction) CSAT (Customer Satisfaction Score) is a metric that measures how satisfied your guests are with a specific experience, such as a stay, the check-in process, a front-desk interaction, or breakfast. It comes from a direct question like 'How satisfied were you with your stay?' that guests answer on a scale (for example, 1 to 5 or 1 to 10). Read definition Direct Booking A direct booking is a reservation made straight with the hotel, without intermediaries such as online travel agencies (OTAs). It can come through the hotel's website booking engine, phone, email, WhatsApp, or at the front desk. Read definition Flexible Hotel Pricing Flexible pricing, or dynamic pricing, is a pricing strategy in which the room rate changes dynamically based on demand, occupancy, season, competition, and other market factors. Instead of holding a fixed price all year, the hotel raises rates when demand is high and lowers them when bookings need a boost. Read definition GOPPAR GOPPAR (Gross Operating Profit Per Available Room) is the metric that measures a hotel's real profitability per available room, after operating expenses are deducted. Unlike RevPAR or TRevPAR, which look at revenue, GOPPAR shows how much profit is actually left. Read definition Guest Complaints Guest complaints are the expressions of dissatisfaction a customer shares with the hotel when something falls short of expectations: cleanliness, noise, a charge, a service or staff conduct. They arrive at the front desk, by message or phone during the stay, or publicly, in reviews and on social media, after departure. Read definition Guest Data Privacy Guest data privacy is how a hotel collects, stores, uses and protects its customers' personal information: names, ID documents, contact details, payment data, preferences and spending. Because every booking, check-in and conversation handles sensitive data, protecting it is both a legal obligation and a condition of guest trust. Read definition Guest Retention Guest retention in hospitality is the set of strategies and actions aimed at encouraging a guest to return to the property and recommend the brand, rather than choosing a competitor for their next trip. It goes beyond a single satisfying stay: the goal is to build an emotional, trust-based relationship that lasts over time through personalization, recognition and attentive care before, during and after the visit. Read definition Hotel Accessibility Hotel accessibility is the set of measures that allow any person, regardless of mobility, vision, hearing, or cognitive ability, to book, arrive, stay, and use the hotel's services independently and safely. It spans everything from physical infrastructure, such as ramps, adapted elevators, and accessible bathrooms, to communication, the website, and guest service. Read definition Hotel Booking Channels Hotel booking channels are the routes a hotel uses to sell its rooms and reach guests. They include direct channels such as the hotel's own website, booking engine, phone, or WhatsApp, and indirect channels such as OTAs, metasearch sites, traditional travel agencies, and GDS. Each channel carries a different cost, reach, and guest profile. Read definition Hotel Booking Engine A booking engine is the software that lets guests check availability, view rates, and complete a reservation directly on the hotel's website, without going through an OTA. It processes the booking and usually the payment, integrating with the PMS and channel manager. Read definition Hotel Chatbot A hotel chatbot is a software program built to hold automated conversations with guests and prospective customers across channels such as the hotel website, WhatsApp, social media or the booking engine. Its purpose is to answer questions, handle requests and guide users toward a booking without needing a human agent in every interaction. Read definition Hotel Check-out Check-out is the process by which a guest ends their stay, returns the room and settles any outstanding balance. It typically involves reviewing charges, issuing the invoice and confirming departure, which releases the room for cleaning and the next assignment. Read definition Hotel Cross-selling Hotel cross-selling is the sale of products and services that complement the guest's main stay: dinner at the restaurant, spa treatments, airport transfers, excursions, parking, or local experiences. Unlike upselling, it does not improve the booked room; instead it adds extra revenue around it. Read definition Hotel Digital Marketing Hotel digital marketing is the set of online strategies and channels a hotel uses to attract guests, generate demand, and convert it into bookings, ideally direct ones. It ranges from search engine optimization (SEO) and paid advertising to social media, email marketing, metasearch, and online reputation management. Read definition Hotel Guest Apps A hotel guest app is a digital application, mobile or web based, that a hotel provides so guests can manage their stay from their phone. Through it, a guest can check in, unlock the room door, order room service, book services, browse hotel information and message staff without going through the front desk. Read definition Hotel Housekeeping Housekeeping is the department responsible for cleaning and maintaining guest rooms and common areas across the hotel. It covers tasks such as daily cleaning, changing linens and towels, restocking amenities and preparing rooms after each departure. Read definition Hotel Metasearch Hotel metasearch engines are platforms that compare, in one place, the prices of the same hotel across different channels, such as OTAs and the official website. Well-known examples include Google Hotels, Trivago, Kayak, and TripAdvisor. Unlike an OTA, a metasearch site does not process the booking: it redirects the user to the chosen channel to complete the purchase there. Read definition Hotel No-Show A hotel no-show is when a guest with a confirmed reservation fails to arrive on the expected check-in date and does not cancel beforehand. The room stays blocked and, unless the rate is fully refundable, a charge is usually applied according to the property's policy. Read definition Hotel Occupancy Rate Hotel occupancy rate is the percentage of available rooms that are sold over a given period. It's one of the most fundamental and closely watched metrics in the industry because it directly reflects how much demand the hotel is capturing relative to its real capacity. Read definition Hotel Online Reputation Online reputation management is the set of practices a hotel uses to monitor, influence, and improve how guests perceive its brand across the internet. It covers reviews on platforms such as Google, TripAdvisor, and Booking.com, social media comments, metasearch mentions, and any public content that shapes a prospective guest's decision to book. Read definition Hotel Overbooking Hotel overbooking means accepting more reservations than there are available rooms for a given date. Though it sounds risky, it's a deliberate revenue management practice: it aims to offset cancellations, no-shows and early departures so the hotel doesn't end up with empty rooms it can no longer sell. Read definition Hotel PMS A PMS (Property Management System) is a hotel's central management system. It centralizes daily operations: reservations, room assignment, check-in and check-out, billing, room status, and guest data, acting as the single source of truth for the operation. Read definition Hotel Room Service Room service is the option that lets a guest order food, drinks or other items and have them delivered directly to their room. It is a classic hospitality service that pairs guest convenience with an extra source of revenue for the hotel. Read definition Hotel Room Types Hotel room types are the categories a property uses to classify its units based on capacity, bed configuration, size, and included amenities. This classification helps organize inventory, set differentiated rates, and clearly communicate to guests what they will get when they book. Read definition Hotel Staff Shortages Hotel staff shortages are the difficulty of filling the roles needed to operate normally, whether due to a lack of candidates, high turnover, seasonality, or competition from other industries for the same talent. They hit areas like the front desk, housekeeping, and food and beverage hardest, where the workload is intensive and heavily people-dependent. Read definition Hotel Star Ranking System The star ranking system classifies hotels according to the level of services, facilities, and quality they offer, typically from one to five stars. Its purpose is to give travelers a quick reference for what to expect before they book. Read definition Hotel Tech Stack A hotel tech stack is the set of systems and technology tools a hotel uses to operate and sell. It usually includes the PMS at its core, along with the channel manager, the booking engine, the payment system, revenue management tools, the CRM and guest communication solutions. The key is not just which tools you use, but how they connect to one another. Read definition Hotel Upselling Hotel upselling is the technique of offering a guest a higher-end version of what they are already buying or have booked, in exchange for an additional charge. The classic example is proposing a room category upgrade (from standard to superior, from superior to suite) or a better-view upgrade, but it also covers rates with breakfast, late check-out, or higher-value packages. Read definition Hotel Virtual Assistant A hotel virtual assistant is AI-powered software that serves guests conversationally before booking, during the stay and after check-out. Unlike a simple chatbot, it doesn't just answer: it checks availability, quotes, handles requests, recommends services and hands off to a person when needed. Read definition Hotel Voice Assistant A voice assistant is an artificial intelligence system that understands spoken language and replies with a natural-sounding voice. It combines automatic speech recognition (which turns audio into text), language models that interpret the guest's intent, and speech synthesis that generates a spoken response. Unlike a generic smart speaker, a hotel voice assistant connects to the property's systems so it can resolve real guest requests. Read definition Hotel vs Hostel A hotel is an establishment that offers private rooms with en-suite bathrooms and a range of services such as 24-hour reception, daily housekeeping, on-site dining and room service, all designed around guest comfort and privacy. A hostel, by contrast, is a more budget-friendly option that typically offers beds in shared dormitories (though private rooms are often available too), along with communal spaces like a kitchen, lounge or social areas that encourage interaction between travelers. Read definition Hotel vs Motel A hotel is an establishment built for one- or multi-night stays that offers private rooms, a reception desk, and services such as daily housekeeping, dining or a spa, and is usually located in urban or tourist areas. A motel is an accommodation aimed mainly at road travelers: it sits near highways or main roads, offers direct room access from the parking lot, and focuses on short stays with a more limited level of service. Read definition Hotel vs Resort A hotel is a lodging establishment that offers rooms and core services such as a reception desk, housekeeping and sometimes a restaurant, and is typically designed for guests to sleep and then head out to explore the destination. A resort is a much larger, self-contained vacation complex, usually located in beach, mountain or nature settings, that combines accommodation, dining, pools, a spa, activities and entertainment all within the same property so guests never need to leave. Read definition How to Calculate Hotel Metrics Hotel metrics are the indicators that let you measure your property's performance, compare periods, and make revenue management decisions based on data rather than gut feeling. The most important ones are occupancy, ADR, RevPAR, RevPOR, GOPPAR, and ALOS, each with a simple formula that answers a different business question. Read definition LLM (Large Language Models) An LLM, or large language model, is a type of artificial intelligence trained on huge amounts of text to understand and generate human language. It learns the patterns of language and uses them to predict and produce coherent text, answering questions, drafting messages, summarizing information, or translating. The models that power ChatGPT, Gemini, and Claude are examples of LLMs. They are the foundation of today's generative AI. Read definition Luxury Hotel Segment Luxury hotels are upscale properties (typically four- and five-star, as well as higher tiers such as ultra-luxury) that offer exceptional facilities, flawless service and a highly personalized experience. They are defined by the quality of every detail: premium amenities, signature dining, spa, butler service and staff-to-room ratios well above average. Read definition Multi-Property Management Multi-property management is the ability to run several hotel properties, whether owned individually or part of the same chain or group, from a single platform or centralized structure. It lets you control bookings, rates, inventory, staff, and reporting across all properties in one place, instead of operating each hotel in isolation. Read definition Multimodal AI Multimodal AI is a type of artificial intelligence that can understand and generate information across several formats at once: text, voice, images, audio, and even video. Unlike models that only process text, a multimodal system can, for example, read a photo a user sends, interpret what they say by voice, and respond by combining words and images, grasping context more completely. Read definition NLP (Natural Language Processing) NLP (Natural Language Processing) is the branch of artificial intelligence that enables machines to understand, interpret and generate human language, both written and spoken. It's the technology that turns a free-form message like 'do you have a room with a crib for the weekend?' into a clear, actionable intent for a system. Read definition Omnichannel Hospitality Omnichannel hospitality is the strategy of integrating all of a hotel's communication and sales channels (WhatsApp, website, email, phone, social media, OTAs and the front desk) into one continuous conversation. Unlike a multichannel setup, where each channel works in isolation, a guest can start on Instagram, continue on WhatsApp and finish at the front desk without repeating anything. Read definition Online Check-in Online check-in is the process that lets guests complete their arrival registration before reaching the hotel, from their phone or computer. Instead of filling out forms and showing documents at the front desk, the guest provides their details, uploads their ID, signs the registration and, in many cases, selects preferences or add-on services digitally, usually in the days or hours before arrival. Read definition OTA Commissions OTA commissions are the percentage that online travel agencies such as Booking.com, Expedia, or Hotels.com charge a hotel for each reservation generated through their platforms. They are deducted from the value of the stay and charged only when a booking materializes. Read definition OTAs for Hotels OTAs (Online Travel Agencies) are online travel agencies that sell accommodation through their platforms, such as Booking.com, Expedia, Hotelbeds, or Airbnb. They concentrate huge traffic and visibility, process the booking end to end, and charge the hotel a commission on every confirmed stay. Read definition RAG (Retrieval-Augmented Generation) RAG, short for Retrieval-Augmented Generation, is a technique that connects a language model (LLM) to your own knowledge base. Instead of answering only from what it learned during training, the system first retrieves relevant information from documents, databases, or specific systems, and then generates its answer based on that retrieved material. Read definition Rate Parity Rate parity is the principle by which a hotel keeps the same price for the same room and conditions across all online sales channels, whether OTAs like Booking or Expedia, metasearch engines, or its own website. It aims to prevent one channel from showing a lower price than another, which would confuse guests or undermine their trust. Read definition Repeat Hotel Guests Repeat hotel guests are those who return to the property regularly, whether for business, holidays, or brand affinity. They are the foundation of loyalty: they know the hotel, trust it, and tend to book directly rather than through online travel agencies. Read definition Reservation Confirmation A reservation confirmation is the message a hotel sends a guest to verify that their booking request has been recorded and secured. It serves as the formal record of the transaction and includes the essential details of the stay: guest name, check-in and check-out dates, room type, rate, confirmation number, and cancellation terms. Read definition Revenue Management Revenue management is the practice of selling the right room, to the right guest, at the right price, at the right time, through the right channel. Its goal is to maximize hotel revenue by adjusting rates and availability based on forecasted demand, competitor pricing, booking lead time, and historical guest behavior. Read definition RevPAR RevPAR (Revenue Per Available Room) is the hotel metric that combines occupancy and average rate in a single figure. It is calculated by dividing room revenue by available rooms, or by multiplying ADR by occupancy, and shows how much every room in the hotel earns, whether it is sold or sitting empty. Read definition RevPOR RevPOR (Revenue Per Occupied Room) measures how much total revenue each occupied room generates, combining lodging and every additional service the guest consumes. Unlike RevPAR, which spreads across all available rooms, RevPOR focuses only on the rooms that were actually sold. Read definition Satisfaction Surveys Satisfaction surveys are structured questionnaires a hotel sends to guests to measure how happy they are with different aspects of their stay, from booking and check-in through cleanliness, service, and value for money. They are typically sent during the stay or right after checkout and are the primary tool for capturing the guest's voice in a direct, actionable way. Read definition Shoulder Season Shoulder season, often used alongside low season, is the time of year when demand for a destination or hotel falls noticeably, leading to lower occupancy, softer rates, and a reduced RevPAR. It is typically tied to weather, school or work calendars, and each market's own seasonality, so the exact dates vary by location and property type. Read definition Slow Tourism Slow tourism is a calm, mindful way of travelling that favors enjoying a few places deeply over rushing through many. The slow traveller prioritizes connecting with local culture, nature, regional food, and wellbeing, and rejects the logic of fast, mass tourism. Read definition Sustainable Hotels A sustainable hotel is one that embeds environmental, social and economic criteria across its entire operation to reduce its impact and add value to its surroundings. This includes energy and water efficiency, responsible waste management, sourcing from local suppliers, fair labor conditions and, in many cases, recognized certifications such as LEED, EarthCheck, Green Key or Travelife. Read definition TRevPAR TRevPAR (Total Revenue Per Available Room) measures how much each available room generates when you count all of the hotel's revenue, not just lodging. It includes restaurant, bar, spa, events, parking and any other service that brings in income. Read definition Types of Tourist Accommodation Tourist accommodation covers all the lodging options available to travelers, from large hotels to apartments, hostels, or country houses. Each type serves a different traveler profile, budget, and experience. Read definition Types of Travellers Types of travellers are the different guest profiles a hotel hosts based on their motivation, buying behavior, and expectations. Understanding them lets you segment your messaging, tailor rates and services, and deliver a relevant experience to each guest instead of a one-size-fits-all approach. Read definition VIP Hotel Guests VIP hotel guests are a property's highest-value clients: celebrities, senior executives, high-spending regulars, or guests with special needs who require exclusive treatment. What defines them is not just budget, but the expectation of personalized, discreet, and anticipatory service. Read definition Virtual Concierge A virtual concierge is a digital assistant that delivers the information and services traditionally handled by the front desk or concierge, but through digital channels such as chat, WhatsApp, an app, or an in-room panel. It answers common questions, recommends restaurants and activities, handles room service or housekeeping requests, and helps with check-in, all automatically and available around the clock. Read definition Welcome Messages Welcome messages are the communications a hotel sends to guests at three moments: when the booking is confirmed, ahead of arrival and at check-in. They share useful information in advance, create a good first impression and open a channel of dialogue that eases the traveler's uncertainty. Read definition WhatsApp Business for Hotels WhatsApp Business is the business version of WhatsApp, and for a hotel it is the way to serve guests on one of the world's most-used messaging channels. It comes in two forms: the free app, for a single device, and the WhatsApp Business API, the official way to connect the number to software, automate conversations, serve guests with several agents and send verified templates.
