We just got back, too! (3-15 to 3-22)
The crowds were not bad at all except in Fantasyland at the MK. Peter Pan's Flight was up to a 90-minute wait at one point on Friday, while Space Mtn. and Splash Mtn. only had 15 to 20-minute waits! Pooh also had a really long wait.
We never had to wait more than 15 minutes for anything--a lot of rides we just walked on, especially at Epcot (boy was it deserted there!). I found we got a lot more done avoiding EE and going to a non-EE park at opening. I will never do EE again--not worth the hassle!
