Use Lockers You can use or rent one so your belongings are safely locked away. You will probably have to bring your own lock, so you will be the only one who can access your belongings. If there are no lockers available, you can also purchase a backpack with a built-in lock so your belongings are safe.

In 2026, the most reliable way to secure your belongings at a water park is to utilize the electronic locker systems now standard at major parks like Volcano Bay or Typhoon Lagoon. These lockers are typically linked to a "smart" waterproof wristband (like a MagicBand or TapuTapu), allowing you to lock and unlock your bin without carrying a physical key. For those who prefer to keep items with them, waterproof fanny packs or "dry bags" with a triple-seal closure have become highly popular; these allow you to keep your phone and credit cards on your person even while on slides. A low-tech "decoy" trick involves cleaning out an empty, opaque sunblock bottle and hiding your cash and keys inside it—thieves rarely look for valuables in a bottle of SPF 50. However, the golden rule for 2026 remains "less is more": only bring one form of payment and your ID, leaving jewelry and expensive electronics in your hotel safe or car trunk.
