Yes, Flame Tree is all outside. The pavillions down by the water aren't too bad in this heat, and last time we were there, a boat went by with the characters singing and dancing on it. However, next week I'm going to WDW and hate extreme heat, so I'm going back to Pizzafari this time, where they have a delish hot Deli sandwich and last time I was there, they had frozen lemonade. A table in the back room made it pretty (relatively speaking) quiet.
