The price of the water park is included with the room.
The size of the room also determines the number of wristbands. I believe limited extra wristbands are available for $50 each but their goal is to limit it to occupants. We had two friends come and we bought bigger rooms to include extra wristbands for them, even though they were not staying.
They give you wristbands I think 4 come with the room and I think 3 and under are free (might be 2)
You can have daily passes to use the waterpark that you can buy in addition for others you may want to use the waterpark for like a party. I've done it many times
You have to have a room to get access to the waterpark.
I know it's worth it.
