We were there at the end of August last year - MK hours for 8/18-24 were all extended until 11 PM - the Studios on the last week 8/25-31 had hours 9AM - 10PM on Sun, Mon, Tues, Thurs and Sat - on Weds they closed at 6 and on Friday they closed at 8:30 - Animal Kingdom varied from 5,6 &7 PM closings from the 18th-24th. I'm pretty sure those hours were all extended from the time when they were first posted.
