Disney Vacation Club resorts' high occupancy level and limited housekeeping schedule present some challenges on check-out days. Nearly all rooms must be turned-over by 4pm for newly arriving guests. Many of those rooms have not been serviced for up to 7 days. With only a few hours to clean dozens or hundreds of rooms, housekeeping staff have been known to knock on doors searching for vacated rooms which are ready to be cleaned. Late check-outs are not granted under any circumstances.
