We were there this past year for Halloween after we got off the WONDER.... It was busy,but not overlycrowded....We never really waited more that 10-15 minutes for anything. We used fast pass if waits were more than 30 minutes...
If you get a chance go to
MNSSHP at MK while you are there. That was a lot of fun. We made the mistake of going on Halloween night

It was very busy (SOLD OUT),but we still really enjoyed our selves. The lines were not long,but LOTS of people

Everywhere...Ecspecially on Mainstreet USA.
We managed to see both parades and the kids trick or treated. Lots of neat costumes and the park was fixed up so cool for Halloween. If you can go to a party early in the month it would be perfect!!!
We also did MGM while we were there and it was not bad at all. We had a blast...
Good luck with your planning. Also the weather was near perfect! It was hot,but not really that humid like Summer time. The party that night it was about 70 degrees and a perfect evening. Have fun!
