What is there for the adults to do.

Outside of the big water slides and bars, not much. That being said, if you're worried about having stuff to do after dumping off the kids, you're probably not doing it right.

Raft rides. Bars. Arcade. Put put golf

This is 90% kid, but there is a bar and you can drank everywhere
