Yup -- I was there in Sept last year and Oct two years ago, just got back this week and the crowds were much worse than they've been in past years, and in fact were the worst I've seen them since my Jan 99 trip. But, despite that, we still got a LOT in, and some days were worse than others. MK was the worst, with wait time for Splash averaging about 40 minutes (80 minutes at one time, but I think that was because it had been down all morning).
But, using Fast Pass, we never waited more than 20 minutes for anything.
