We put in for an Interval exchange in Spring 2006 for Fall 2006 and we were very lucky and received the Marriott Scottsdale, 5 miles from my sister's house. Very nice resort and we listened to their timeshare spiel and receive a $100 gift card for dinner. We knew going in that we would not bu so it wasn't a big deal.
We did find the resort convenient and close to everything.
Good luck
