Must be perspective, we were there on the 18th and left yesterday. I thought crowds for the most part were low, the usual long waits for Toy Story, Soarin, Rock-N Rollercoaster. But most other rides (that we did) were only 10-20 minutes.
I found that although the guides steer you away from extra magic hours, we get a ton of rides in between the hours of 9 to midnight. Haunted Mansion was 5 minutes, Space Mtn the same. I guess it is timing, but we thought the crowds were very manageable. We did not go to a Park on Saturday if that means anything. Sunday at HS was probably the busiest park we experienced. We did EPCOT midweek because of F&W, and the only ride with a real wait was Soarin. Test track we did the first time in about 10 minutes, saw it was up to about 45 at one point, but we did the ride twice with no longer than 20 minute wait.
Good luck, hope crowds are low for you!
