Hotels can be classified in various ways, including by location, size, level of service, length of stay, theme, and target market. Some of the main categories are city center hotels, motels, resort hotels, small hotels with 100 rooms or less, large hotels with over 300 rooms, economy/budget hotels, luxury hotels, transient hotels for short stays, and resort hotels that cater to vacationers seeking relaxation. The hotel industry encompasses many different property types that do not always fit neatly into single categories.
