A hotel is an establishment that provides lodging paid on a short-term basis. Facilities provided may range from a basic bed and storage for clothing, to luxury features like en-suite bathrooms. Larger hotels may provide additional guest facilities such as a swimming pool, business center, childcare, conference facilities and social function services. Hotel rooms are usually numbered (or named in some smaller hotels and B&Bs) to allow guests to identify their room. Some hotels offer meals as part of a room and board arrangement. In the United Kingdom, a hotel is required by law to serve food and drinks to all guests within certain stated hours. In Japan, capsule hotels provide a minimized amount of room space and shared facilities. The precursor to the modern hotel was the inn of medieval Europe. For a period of about 200 years from the mid-17th century, coaching inns served as a place for lodging for coach travelers. Inns began to cater for richer clients in the mid-18th century. One of the first hotels in a modern sense was opened in Exeter in 1768. Hotels proliferated throughout Western Europe and North America in the 19th century, and luxury hotels began to spring up in the later part of the century.

Hotel operations vary in size, function, and cost. Most hotels and major hospitality companies have set industry standards to classify hotel types. An upscale full-service hotel facility offers luxury amenities, full service accommodations, on-site full service restaurant(s), and the highest level of personalized service. Full service hotels often contain upscale full-service facilities with a large volume of full service accommodations, on-site full service restaurant(s), and a variety of on-site amenities. Boutique hotels are smaller independent non-branded hotels that often contain upscale facilities. Small to medium-sized hotel establishments offer a limited amount of on-site amenities. Economy hotels are small to medium-sized hotel establishments that offer basic accommodations with little to no services. Extended stay hotels are small to medium-sized hotels that offer longer term full service accommodations compared to a traditional hotel.
