1) That is not how the key system at WDW works.
2) If the next guest checks in, their keys will work for your room.
3) If they activate the door, your keys are no longer valid.

5) DVC rooms (OKW-SSR-VWL-BCV-AKV-BWV) do not allow late check-outs.
6) Other resort late checkouts are permitted by Housekeeping, not the Front Desk.
7) It depends upon
. . . number of check-ins and check-outs that day
. . . occupancy of the resort the night before
. . . how nice you talk to Housekeeping
. . . staffing and/or absenteeism of maids
. . . phase of the moon
8) If allowed,
. . . check-out 11:00am-1:00pm, no charge
. . . check-out 1:00pm-3:00pm, up to 50% of the room rate
. . . check-out 3:00pm or later, up to 100% of room rate
