Planning a 2 week trip to include a week or so in the Florida Keys followed by a few days at Disney. Crowds should be on the lower side as US kids generally go back to school mid August which is the reason we’re looking at this time of year BUT my concern is the heat and humidity. We don’t mind, for example, south of France in summer so hoping we can handle the Florida heat. Plus plenty of air con? Would we be crazy to go in August? Anyone out there with experience?
