How does admission to Thrill Waterpark work on Perfect Day at CocoCay? Can I exit and enter the park as I please?

If you have pre-purchased your Thrill Waterpark admission, you may swipe your SeaPass card at the park entrance to enter. You may also purchase admission to the waterpark, once you are on the island, using your SeaPass card at the park entrance. If you wish to leave the waterpark during your day, you’ll be given a wristband so you may enter and exit the park as often as you like.
