We employ hundreds of lifeguards who have extensive training in monitoring pools and operating rides. We also contract with a company that independently audits lifeguard performance and vigilance. We would like to remind parents that although we have award-winning lifeguards, they are not a substitute for responsible parental supervision. Always keep your child within arm's reach, and if your child is in the water, you should be, too.
