So many people have been complaining about the brutal heat we should make a list of places to go where they can escape. You can go on a water ride but a lot of people don't like to get soaked. Here are some I can think of right off the bat that are enclosed so the line wait is out of the sun and/or air conditioned:
USF
Terminator
The Mummy
MIB unless it's a massively crowded day
The Horror Makeup Show
IOA
Hulk
Dueling Dragons
Spiderman
Cat In The Hat
Poseidon's Fury
Plus there are restaurants in both parks and you can duck into the various shops. Feel free to add others I've forgotten.
