I was there the week before Halloween. MGM and AK were not crowded AT ALL. EPCOT and MK were another story, but with regards to EPCOT you must take into consideration that the F&W fest. was going on at the time.
We found MK extremly crowded for this time of year. We came to the conclusion that the guest influx must have been from Hurricane Wilma as that it had just rolled in. It seemed that where ever we turned we ran into the families that were 'escaping the hurricane' and had gone to WDW to get hot water, electricity, and an escape from reality. During our wait in one line at the MK we had the family in front of us 'escaping the hurricane' and the family behind us 'escaping the hurrincane'. Just from that instance we assumed that there were a lot more people in the park than normal for that time of year due to the hurricane.
In short, I would not hesitate at all from going to WDW again at time. Actually we are planning on going again once my Hubby gets out of graduate school...in 2008.
