A swimsuit
While you might be thinking ‘duh, of course I’ll need a swimsuit!’, but its important that you bring an all-in-one style suit as well as a two piece bikini, and the reason for that is science..
Picture the scene: Blizzard Beach or Typhoon Lagoon, scorching Florida day, nice big slide opening out into a pool full of people, and while gravity might be pulling your body down, your top is going to want to stay put and fly back up. Its happened to everyone, embarrassing or what?
So save the bikini for the hotel pool or lying out in the sun, and save your dignity by packing a one-piece for the waterparks! 🙂
