Last year we went to MGM on super soap weekend. Surprisingly, the park was crowded, but the ride lines were actually short. Still, getting a round was a bit of a pain. I really hate slow walkers who spread out across the pathway in a group of five or so, or those who stop to study their maps five across the pathway, ignoring the people behind them who are blocked...but enough.
I think we also went over to Epcot the same day. It's still the F & W festival, right? So there will be some crowds for that, but it wasn't too bad. The only thing we found wa sthat the wait for some foods/free wine was longer than we were willing to wait. It is an interesting time to go to Epcot though. The WS has lots of extra stuff.
