This is the same size as the other water parks in the area, it has a theme like the other water parks in the area, while I am excited that it has some thrill rides, it is still a water park. It won't be priced as a theme park. If they do, it will be a mistake. People will just go elsewhere. While it is cool and probably worth an extra $10 a day, no way this is worth $50 more than the other water parks.
Also, I think it is a huge mistake to market it as a 3rd park. it is not a 3rd park. It is a water park and should be marketed as a water park. Tourist get sooooo confused over the simplest thing. Can you imagine them going to the "3rd theme park" and not realizing it is a water park?
