Darryl, sounds like Diamond Club to me. They keep saying they are discontinuing that program. If you buy a second timeshare, you are given access to an RCI site that lists available exchanges. It had "last call" at the top, but it had a lot more resorts than I can see on Last Call. And you could use any week [Silverleaf, I presume] to exchange rather than pay for an extra week. When they quoted prices for the Presidentials at Seaside, I turned off.
