We went once in August many years ago and have not been back in the summer since, yuck! We were already planning a trip to the area just to visit family, so no theme parks, but DAH came up the day before we planned to be there, so we added a day. As much as you think it is just as warm at home (we are in the Chicago area), the same temperature in FL feels much worse due to humidity. I figure we will be okay the later it gets, but are definitely prepared for a very hot and humid early evening.
