I just returned today and have to say, there were LINES on Saturday at MK. It was much busier than I expected. You pretty much had to use FastPass. Some of my observations between 2pm-6pm:
Splash Mtn - 90 Mins
Big Thunder Mtn - 40 Mins
Pirates of Carribean - 30 Mins
Peter Pan - 60 Mins
Pooh's Adventure - 60 Mins
AK on Thursday wasn't bad. Longest wait was 30 Mins for EE. MK on Friday was busier too than a typical "slow month" of September, but nothing like Saturday. Not sure what was going on?
Love bugs were out in force on Wed/Thr, but seemed to be not as bad around the resort on Fri/Sat.
