i'd say the crowds wouldn't be as bad for Columbus Day as they would spring break.
I saw MIB 60 min...can't remember what Simpsons was (stayed at PBH), but the line I did remember seeing, didn't seem all that long.
I know FJ was posted 75 min around 2-3pm on Sat. We did it because out of the 4 of us, BIL was only one who didn't do it yet. We were loading within 45min. actually. Line was steadily moving.
sorry not more help, but i don't really look at standby times because we ALWAYS stay onsite.
