They have the stamp at the front entrance of Kali, so you don't have to get the paper wet. Can leave it with non-riders. If you know the answers already, you don't need to ride the ride. But, hey, it's a fun ride, and feels great on a hot day.
a pin, a room, and a raft. The raft comes as 4 pieces. I was really hoping to get the "banana chair" or surf board as part of the room, but no luck.
