Its free with the purchase of a room
If you know somebody staying there that doesn't have the maximum 6 occupants an additional person can pay $50 for a pass tied to that room. It could conceivably be used for two days.
Waterpark is only open to guests. If there is a guest staying there that wants to let a visitor come in, it varies based on occupancy. If it is open for that day passes are usually around $50.
