I think it's hard for a lot of people to realize that although it's still HOT as you know what in Florida, Summer can still be winding down, and Fall approaching. We don't really get "Fall weather" here. It's going to be hot no matter what. The Halloween decor being out now is not that big of a deal IMO. The party starts tomorrow. To expect Disney to keep the party only in October for instance just wouldn't work. There are millions of people who want to experience the party, and Halloween in general at the Magic Kingdom. You need a good chunk of time for that. If someone's late August trip is honestly RUINED because they have to see a couple of pumpkins on Main Street, I think it's time to reevaluate things. If this is the case, its best not to visit at this time. I think there are more people excited about the decor than not. I know I am!
