It is def not free.
I am not sure what you mean, but here's something that might help you out. A single day pass costs $47.99 each . But a "splash pass" that gives you unlimited visits to the water park for 2019 season is only $49.99. You have to pay for parking. I forgot... maybe it's $10 or $20 for general parking. For the entire month of June, they have another deal (online only) when you buy a single day pass, you can get another for 50% off. I hope this helps. :)
