Odd, I was there 5/5-5/10 and found the crowds a little larger than normal. 60 min for Soarin, 60 for TSM, 50 for Peter Pan, etc. There were still a good amount of lower waits, but some were even the longest I've seen (one day the line for It's A Small World was almost out the door! It was also much hotter than normal (and you are right, Saturday was VERY hot). I was told by my friend who lives there that it only started to get hot like 2 weeks ago.
