I haven't been in a while, so this is off the top of my head.
I remember the pets a hoy (animal show) is in AC. There are eating places which are inside and ac. I remember the beer school, and seating area was ac. There was some indoor show, I don't remember the name (theatrical show), it was good and indoors. Where the big horses were, was really hot, long lines, fans on the horses,etc.
What I remember was outside, shamu, the sea lion show, the dolphin show.
There might be some overhead shading (I can't rememberhow much, or which show), so if you get to the show early, look for a shaded area.
