We visited Disney last year at the same time and it was very hot-90 each day. We didn't see more than a few drops of rain, but from what everyone on these boards was that it can be very rainy. I know what you mean about having a hard time with the hot weather in NH-we live in Maine and pretty much turn on the air conditioning and stay inside when it gets above 90-but when we were in Florida we just kind of dealt with it-I guess we even got used to it after a while. We found the best thing was to head out of the park at or just after lunch time each day-take a break to nap or swim (we had a 15 month old and a 3 year old) and headed back into the park around three until closing.
