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, simply swipe your SeaPass card at the park entrance to enter. You may also purchase admission to the waterpark, once you are on the island, then use your SeaPass card at the park entrance. If you wish to leave the waterpark during your day, use your SeaPass card to enter and exit the park as often as you like.
