Hotel reservations are bookings made in advance to secure a room at a hotel. Guests can reserve a room through various methods, including online platforms, phone calls, or in-person visits. Reservations typically require personal information and payment details to confirm the booking. Once a reservation is made, guests receive a confirmation, which includes important details like check-in and check-out dates, room type, and any special requests. It is advisable to review the cancellation policy, as changes or cancellations may incur fees. This process helps ensure a smooth stay at the hotel.
