As I was thinking. Volcano Bay would have to have a Roller Coaster of some kind or a few simulators, walk through attractions for it to be a Theme Park of any kind in my book. It's a water park that is themed,highly themed. At Least if I pay $100 for IOA,Universal, Any of the 4 Disney Parks, I know I'm getting multiple types of attractions (granted many repetitive) . I pay a $100 at Volcano Bay and they are all water based slides.Nothing wrong with that, but it does not make it a theme park. However Having thematic elements such as show scenes, characters, street performances, restaurant (Sit down), and guess interaction adventures does help Universal tout it as a theme park.
