We took DD(3) on splash and she cried. It's a little dark and loud inside and I only remembered 3 of the 4 drops before the big drop so I couldn't warn her about the 4th and the tears started. She LOVES thunder mountain though but also hates Nemo (dark and the mine explosion scared her, she cried) and Fantasmic! We did buy the photo though since I figured it'll be a while before I hear "Momma, I wanna ride Splash Mountain" again (she wanted to after seeing it on the
Disneyland sing along songs DVD but not no more)
Edit: Her 40" got her on Splash and Big Thunder but she was too short for the 40" requirement on Soarin'. We would always tell her we'll see if you can ride because we weren't sure if their 40" was the same as the other 40".
