Before you get in line
- Get the wristband first. Kings Island measures at the Information Center just inside the front gate and in Planet Snoopy near Snoopy vs. Red Baron, and the wristband shows the child's height range at every ride.
- Wear normal shoes. The park can ask for shoes to come off if they add height, and platform shoes do not count toward a requirement.
- Bring a companion who also fits. The supervising companion has to be 54 inches, 14 or older and able to ride too.
- Try the test seat. Banshee, Diamondback, Delirium and Orion keep one at the ride entrance.
