This service enables one person to wait with the child while another goes on the ride; afterwards the person waiting with the child may board the ride without having to wait in line. If your child does not meet the ride’s height requirement, there is a “rider swap” service available. Lap children are not permitted on most rides, avengers costumes adults especially if there are restraining devices. Children must be potty trained and be between the ages of 4 and 12 (inclusive).
