The height requirement sign at Mission: SPACEIf you’re headed to Walt Disney World with little ones, look over the height requirements ahead of time. Knowing in advance which rides the kids won’t be able to ride will make things easier on everyone. Try to steer clear of those rides whenever possible. Also, if the child doesn’t quite measure up, don’t blame the Cast Members. No one is trying to ruin your kids’ vacation by keeping them safe. All too often I’ve seen parents tell their children that it was the Cast Member’s fault that they couldn’t ride. That’s not the case at all.
