It means access to exclusive lodging at Disney.
Disney Vacation Club has 14 properties in the US: 10 at Disney World and one each at the nearby Disney's Vero Beach Resort, Disneyland, Hawaii, and South Carolina. Across the board, members (and their guests) pick between Deluxe Studios and one-, two-, and even three-bedroom villas at most locations, and all come with a kitchenette or kitchen and other amenities. I stayed at the elegantly rustic Copper Creek Villas & Cabins at Disney World's Wilderness Lodge (shown here!), which opened late last year, and loved the private hot tub, washer and dryer, and full kitchen.
