One popular piece of nonessential reservation information is the guest’s estimated time arrival. A guest who is planning to arrive late (usually due to a late flight schedule) should ask for this information to be included on the reservation. In this way, the guest is assured that the room will not be sold in the late hours of the night. Without such a designation on the reservation, it is possible that a well-meaning front desk might actually sell the reservation room to another customer thinking that the reservation is not going to arrive.
