It will stay HOT well into the evening!! We live in Houston and from late May-October there isn't a day that feels "cool". Orlando is even a little hotter than here. Trust me being chilled outside is one thing you won't have to worry about. Freezing inside with ac blasting is a whole other issue. I have a sweater at all times here b/c you go from 95 outside to 60 inside!! Enjoy your trip, we leave in 16 days!
