I just got back today, was there 10/21-10/26. I found the parks to be very crowded all the way around. Much more so than 2 years ago (which I expected as the trip 2 years ago was just 6 weeks after 9/11), but I was somewhat prepared after reading the posts in these boards for the past few weeks. Had to make heavy use of FP. I found all 4 parks to be crowded although EPCOT was a bit better than the rest. AK was a zoo, no pun intended! Even MGM was shoulder to shoulder in many cases. MK was crowded, as expected. Biggest surprise was how crowded MNSSHP was! We went on Friday 10/24 and it was packed from beginning to end. Plenty of 2 and 3 year olds still trick or treating in Toontown at 11:30 PM! Lines for rides were ok....some shorter than others...but the sheer number of people surprised me. Lines for candy were long in most cases. No real thinning of crowds after the parades. Atmosphere was great. We did enjoy it but just expected to be able to do more.
