Hi bcbmommy,
Our top 3 choices in preference would be, Beach Club Villas, excellent location and Stormalong Bay. Old Key West and the Villas at Wilderness Lodge.
Bear in mind that no matter where you own you have the opportunity to make reservations at any of the DVC Resorts and because they are all different we've never felt that we are going back to the same place year after year.
We've only ever had one regret on becoming DVC members, we never purchased enough points and have therefore added more over the years.
Best wishes.
