I want to preface this list with the idea that every family likes different rides. For instance, MOST people love The Hollywood Tower of Terror. My family however, hates it. So while I put it on this list, I do understand that not every family will love every ride. That being said, the rides on this list are the most high demand and most popular ride in the parks.
I will leave a short description of each ride along with height restrictions for each as again, each family has different sized members. For those with smaller children, make sure you keep your child's height in mind.
