Jeanne, call the timeshare directly and ask if they will allow you to have resort privileges on your check-out day. Where are you staying?
We've been to several timeshares where we packed our things in our car and officially checked-out. Then we were allowed to continue to enjoy the resort pool, fitness room, game room and lobby/lounge until it was time for us to leave to go to another location - at no charge. Some have even had a shower and/or lockers available in the restroom nearest the pool or fitness room so we could freshen up before traveling.
The timeshare resorts are mostly concerned with getting the rooms emptied on time so housekeeping can get in and prepare for the next week's guests. They don't want other owners waiting later in the day. I'd definitely call them and ask about this.
