Different rides require different height depends on what ride they get on .
Each ride has certain rules and regulations you have to abide by.there are height requirements as well a 6 year old i believe has to be accompanied by an adult due to age and size and again is for the safety of the child and the parks policy.
Some rides require 48" height so they may ask you to ride with one of your kids. But for most part they will be fine on their own. Good luck and have fun.
Yes Willie is right different rides are different height so you might have to accomplish or be on the ride with one of your children
