Well, as the previous poster mentioned the weather can be tricky on both months! the last time we went around Halloween it was 97 degrees with humidity about the same! the time before that we went the end of November and it was a bit chilly but doable. We try to go in October as we are huge fans of the Epcot food and wine fest...if you haven't been, you should try it! if you are a foody at all, that's the thing to do. Whatever you decide, I think it will be a shot in the dark as far as the weather but have a great time!
