A hotel reservation is a process where a guest books a room in a hotel for a specific date and duration. This can be done through various methods, including online booking platforms, travel agencies, or directly with the hotel. Reservations typically require personal information and payment details to secure the booking. Once a reservation is confirmed, the guest receives a confirmation number, which is essential for check-in. It ensures that a room is available upon arrival and may include specific requests, such as room type or amenities. Cancelation policies may apply, depending on the hotel's terms.
