You're going from just below average to average, to extremely crowded. Also, it's going to be stupid hot and humid. We're normally October goers, but we went for a SWW last year in June. We did one MK day during that trip, and while crowds weren't as bad as I expected, what I noticed was that the guests were way more testy with each other. There just wasn't as much goodwill between guests as we were used to. The CMs seemed less chipper, too. I'd be crabby in that heat, too. Heh.
