How can I edit the start or end time of a reservation?

Start times cannot be edited once a reservation is created. If you need to adjust the start time of your reservation, whether short- or long-term, you need to cancel your reservation and remake it with the desired times.

The end time of a reservation can be adjusted for long-term, flexible reservations only. The end time of a short-term or long-term fixed-date reservation cannot be edited once the reservation is created; to have a different end time for one of these reservations, you need to cancel the reservation and create a new one with your desired times.

Remember, a short-term or long-term fixed-date reservation can be canceled up until its start time. Once it has started, you cannot edit your reservation.
