My sons love Tom Sawyer Island. We have been known to spend an hour there. It's a great 'escape' from the park. They need places to get out their energy/climbing needs.
I love all the old Disney stuff, I do wish they had slushies or frozen treats again on the island. If it wasnt for the old stuff I wouldn't bother with Disney World at all. I would just go to Canada's Wonderland and Great Wolf Lodge that would basically do it for me. So as long as there are Tiki Birds and a Small World I will return.
