The document discusses the functions of hotel reservations. Reservations involve booking rooms in advance for future guests, from a few days to a month ahead. The main function of reservations is to help generate future room sales and revenue for the hotel. Reservations staff receive requests from prospective guests, check availability, process the requests by accepting, waitlisting, or denying them, and maintain records of reservations, cancellations, and amendments. Ensuring high occupancy levels for the future is also an important function of the reservations department.
