I was looking at the height requirements for some of the rides at Disney. I noticed the Big Thunder Mountain, Dinosaurs, Everest and some of the other Disney thrill rides have a height requirement of 40". Now Pimeval Twirl has a height requirement of 48'. Is this correct or is it an error on Disney's site. I have seen the Primeval Twirl in person but never been on it but it doesn't look nearly as scarey for a kid as BTMRR or Splash Mountain which again have a smaller height requirements. My 4 ds would love it but he will probably be only 42-26' when we go in Sept.
