I can only comment on Summer Bay. We just got back on an RCI timeshare exhange for 10/16-10/22. It was marvellous. We stayed in a 2-bedroom condo, the room was clean, plenty of amenities (pots, pans, coffee-maker, fridge, fully-stocked flatware, soap, shampoo, towels), the drain was clogged when we first arrived and they came in 30 minutes and fixed it, and gave us a free bottle of red wine.
The resort is very clean, well-kept, lots of friendly people, and has a security gate that is actually *used* (i.e. someone actually maintains a post through the night! Awesome!).
Summer Bay offers a free shuttle bus to any Disney site, and it's $7.00 to SeaWorld or Universal.
Lots of discounts available through their ticket office. For listening to a 1 hr sales pitch, we got two adult five-day passes to SeaWorld/Busch Gardens for $35.00 each!
