We were there last year on veterans day and it was also Super Soap Star weekend at MGM. We avoided MGM that weekend, and headed over to the Magic Kingdom the Saturday night (I think it was the 9th) and the crowds were huge -MK was the only park opened late so everyone went over there. Anyway, I think most people left that Monday, which I believe was actually Veterans Day, so our last day was pretty light. I would check to see when the Soap weekend is this year, and unless you're into that, I would avoid that weekend. Where Veterans' Day is a Tuesday this year, you might be OK to go that week though.
Good luck!!!
