So, while creating info pages on my website for Volcano Bay, it occurred to me that maybe one of the reasons Universal can call this a water theme park, is that it actually has themed lands.
Other than names for their kids' areas, Aquatica, Typhoon Lagoon, Blizzard Beach, and certainly Wet 'n Wild do/did not have separately named areas. (Blizzard Beach comes close with the color names of the different slopes.)
Whereas VB has 4 distinct "lands" if you will. Now, they're all somewhat similarly named and offer much of the same stuff, but they all have their own story and some style differences. And it does make it easier to find the restaurant or attraction you're looking for if you know what section of the park it's in.
The Volcano has the slides in/around the volcano, so that's an easy land to remember.
Wave Village has the wave pool, Waturi Beach and The Reef, so Wave Village seems an appropriate name.
River Village has, well, rivers, but also both of the main kids areas and some multi person slides.
Rainforest Village has a lot of the action-packed stuff: Fearless River, Taniwha Tubes, and Maku/Puihi, the more intense family raft rides.
Looking at the concept art and videos more closely, they each have definable areas with their own paths and stylistic differences. It's not as well differentiated as IOA or MK's lands, but they are different lands, and that does set it apart from other water parks.
Just something I've been thinking about.
