Hotel Reservation is a job that involves managing the booking of rooms in a hotel. It requires the ability to handle customer inquiries, process payments, and ensure that all guests have a pleasant stay. The term 'ROOM' is a four-letter word that is used to refer to the space that a guest occupies during their stay at a hotel. Hotel Reservation staff must be knowledgeable about the different types of rooms available and be able to provide information to customers about the amenities and services associated with each ROOM. They must also be able to manage any changes or cancellations to reservations in a timely manner.
