We just got back last night. We were in the parks from Thursday, 5/29 - yesterday. Magic Kingdom was MUCH less croweded than basically the same time last year. On 5/29, we arrived by opening. We pretty much got on everything all day in less than 20 mins. (Most were 10 or less.) By the time we got to Fantasyland, there were 40-60 minute waits for Pooh and Peter Pan. We left in the early afternoon, so I don't know if it got more crowded later. MK was empty yesterday. We arrived around 9:30. We rode Space Mountain TWICE with no waits. (I mean, when we got to the top of the que, there was NO one in front of us. We were the ONLY people in our "ship".) We rode a third time with about a 3 minute wait. We rode HM and went straight into the "room". We walked right on to POTC. We waited less than 10 mins. for BTMRR. Now, that being said, we went a couple of evenings and there were longer waits. There were MANY more people there. (I think the Space Mountain wait was 60 mins., althought we didn't ride it.)
AK & HS were similar to MK. Although, MK was the least crowded "day" park we went to. (The only exception was the new Toy Story ride as HS.) There were HUGE waits for that. We did the single rider line and waited up to 30 minutes each time. (This ride is AWESOME!! Don't miss it.)
Epcot was the most crowded. Soarin' and Test Track had long waits, even early in the day. (We hit them when we arrived, or did the TT single rider line later in the day.) I believe one evening, the single rider line for TT was 25 mins. and the regular 75 minutes.
All in all, it was a great trip! (My parents car got broken into in the HS parking lot and his brand new $400 TomTom GPS, which was hidden in the console, and my son's Gameboy DS were stolen. AND, my family missed our Magical Express bus by 3 minutes because it took an hour from the time we got to the HS bus stop until the bus let us off at POFQ. ME basically told us tough luck. And we had to take a cab. Now, we will obviously plan more of a "buffer" into our next trip to arrive before ME pick-up time. But ME could have handled things a little more professionally on the phone.)
