Wow! That really surprises me. As I said before, we were there August 13-26. The first week we stayed off-site. We always were at the parks by opening and were in the 1st-2nd row of parking. I thought crowds were very light. At MK we almost never waited more than 10 minutes for anything, though we did make use of Fastpass. We started in Frontierland and rode Splash and BTM several times each with no lines. We went to the Fantasyland EMH twice, and there were NO waits for anything. The characters were all out playing games. I don't think that we went to any other Extra Magic Hours. At AK, we rode Expedition Everest at opening with no wait and also got a FastPass to ride it about 40 minutes later. Kali had no wait in the meantime. We rode the Safari several times with less than a 10 minute wait. On the 19th, World Showcase looked almost deserted. We road Soarin' at opening with almost no wait and also picked up FastPasses a couple of other times.
I agree - the parks were always less crowded early in the morning. We only got to MK and AK once for early morning hours. We were able to accomplish a lot in Fantasyland, and rode Expedition Everest without any wait. However, as it got later in the morning, the crowds really started increasing. We usually stayed in the parks for most of the day and night and they were always busy. We hopped around alot on this trip also because of our dining plans and it seemed like every park we went to on a particular day was crowded. It wasn't unusual to see 80 minute waits at the popular attractions. With fastpasses though we were able to do just about everything (we never could fit Test Track in - it just never worked out for us on this trip)!
