My nephew and I were there last July. I made sure to pick an air-conditioned place for lunch. I think it was Voyager's Wood Fired Pizza. Other than that, it is pretty much an open area. There is a SHORT film about the manatees. There are also small underwater viewing area for the manatees and dolphins. And the penguin and shark exhibit are both inside. Not places to relax, but at least it'll get you out of the sun for a while.
