Some things as I catch up on this thread.
The biggest problems Disney theme parks have in Florida:
1. Price
2. Price
3. Price
4. Bob and Josh ignoring 1-3
And despite what Bob or anyone else wants to claim, it has always been hot in Orlando in the summer. A. L. W. A. Y. S. Does 93F with 85% humidity really feel different than 95F with 85% humidity because some weather hypers and doomsayers claim it is? It doesn't to me. I walked out of our room in the morning, in the mid-2000's in the middle of July, and had sunglasses immediately fog over. Guess what? That hasn't changed in 20 years.
Dining is a major problem, particularly around offerings and pricing. I have long held the belief that pricing 10-17 year olds as "adults" was idiotic. TDO has done a fantastic job of watering down menus and essentially bungling many of their restaurants in their quest for more money.
