Come with Liberty to Hawaii's only water park in Kapolei.  Wet 'n' Wild will be open from 1030 to 1600 so bring your sunscreen.  There are lockers inside the park to put your belongings, they are $13 for the small locker so we can split one if you don't need a whole locker.  Bring your swim clothes, towel, sunscreen, and money for lunch.
