I just checked their website & came up with this on their tips page -
When enjoying rides and attractions, obey posted age and height restrictions, as well as notices concerning such health matters as heart conditions, back/neck conditions, pregnancy, recent surgery, and high blood pressure. Always use common sense … if you don't feel well, if there has been an abrupt change in your physical status, or any other unusual or unexplained symptoms, skip the ride.
So I'd just check each ride before you go on to see what it says....
