I really enjoyed Tom Sawyer Island. As a kid I loved the barrel bridge. As an adult, I got to feel like a kid again, exploring in a way you don't get to do anymore when you grow up. It had been like seventeen years since I last went, so I didn't remember what was on there (except for the bridge), and I got really excited about looking around. It was like taking a hike, if you knew you were guarunteed to actually find something other than more trees around each turn.
Don't know, I guess I'm a freak, I made great memories there. It felt unique and fun.
I would think it's at least worth trying some kind of modern IP tie-in before killing it; they have lots of stories involving different places in the woods. Neverland or Wonderland would probably work pretty well, especially considering they clearly don't care about theming anymore.
Just another thing on the ever-growing list of stuff to miss, I guess.
