I went to AK, MGM, and MK yesterday and all of them were so croweded you could barely move!
At AK, Primeval Whirl was 35 min, Safari was 50 mins, those were the two really crowded ones, but the animal trails were filled with people
At MGM, ToT (which I didn't ride) was 120 mins, Rockin' Roller Coaster said 90 mins but seemed longer!
At MK, arrived just as Spectro was about to begin, BAD IDEA! Got to Buzz Lightyear, 45 mins, Space Mountain was 60 mins, Indy Speedway was 30 mins, and Tea cups were only about 10 (sorry would have more but thats all we had time to do)
Also I find an awesome spot to view Fantasy I the sky, stand by Space Mountain, there are few crowds and you have an unobstructed view of the show!
