Villas are assigned on the day of arrival and are based on the check-out pattern for each particular day and are prioritized in the following order:
-Owners in their owner week
-Home owners exchanging into their home resort
-Any other reservations which includes Marriott Owners,
Exchangers, Preview Guests, Rentals,
Non-Marriott owners.
You can always request your preferences but as you see you're very far in the picking order, still good luck!
