Wouldn’t a centralized measuring system with wrist bands stop this? If the kid looks small and doesn’t have a band, CM should measure. If they do have a band, the kid should ride. Done. Simple.It’s not about the close calls after measuring once. It’s about the parents who slip their too small child through when the cast member at the front of the line is distracted with a question from another guest.
Disney uses bands for hard ticket parties. They obviously trust that system because money is involved. And we all know how much the mouse loves money!
