GTD 4PM, in the context of hotel bookings, typically refers to a guaranteed for late arrival reservation held until 4:00 PM on the day following the scheduled arrival date. For example, if a guest books a room with GTD 4PM for arrival on July 10th, the hotel guarantees to hold that room until 4:00 PM on July 11th, even if the guest does not check in on July 10th. This contrasts with a standard reservation, which might be released if the guest does not arrive by a certain time (often 6:00 PM) on the arrival date.
The primary benefit of a GTD 4PM reservation is the assurance that a room will be available even if unforeseen travel delays occur. It provides peace of mind, particularly for guests arriving late due to flight cancellations, traffic congestion, or other unexpected circumstances. Historically, this type of guarantee addressed the needs of travelers who were unable to predict their arrival time with certainty but still required a secure room reservation.
