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 5

PROJECT ON HOTEL MANAGEMENT SYSTEM
INTRODUCTION 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 5
