Disney has posted these requirements for your safety. Print this page out and take it with you. You will have the requirements with you where ever you go.
If you have a child who does not meet the requirements take advantage of the "rider switch" policy. At the attractions where your child is not tall enough to get on, a parent may wait with the child while the other parent rides the attraction. Then switch and the other parent may ride. Be sure you advise the ride attendant.
