When I was there the park closed at 9 and the arcade at 11
I believe 10pm for water park and 11pm for arcade. Hours could be affected by day of the week or time of year. The hours ARE on the website so your best bet would be to look based on when you are visiting.
Water park I thought was 10-9...and I thought the arcade is open all night? I can't remember
Im pretty sure its from 9-10 for tge water parks and the arcades open at 8
