It is up to Mousekeeping, so be sure to check with them. We asked for late checkout once and were told we could have the room until 1:00. Later than that we would have to pay for another night. Even if you can't get late checkout, you can use all the resort amenities the entire day of checkout. If we have a later flight, we hang by the pool, eat, then shower in the locker rooms by the pool and get dressed for the trip home.
