Ron's right (as usual). Nothing shows for Thanksgiving week on the Wyndham website for Floirida or the Southeast.
However, once your contract goes through, you should also be automatically a member of RCI, and therefore would have access to their website. Their "Extra Vacations" website still shows Thanksgiving week rentals for cash in the Orlando/Kissimmee area. Some may be dogs, but you might be able to find a good one by matching up those still available with the TUG Resort Reviews.
