I get what you are saying and comparing, however, Volcano Bay was never suppose to integrate the slides into the landscape. The theme is that the park was ADDED to the landscape, not a PART of the landscape. Typhoon Lagoon is mostly themed to where you are riding 'natural' slides in the landscape that formed from a typhoon. Volcano Bay is a landscape where a water park was added to it. That is why all the slides and supports are exposed, they were added to the environment. This is why the rivers don't have rock work edges, they were man made and are not 'natural rivers'. As I noted earlier in the thread, there are no exposed volcano supports for the rock work, the only exposed supports are for the slides.
I understand why many think the slides and supports should be integrated into the landscape. However, judge the park on what the theme is suppose to be, not what you want it to be. This is not a criticism of what theme is better, more just to point out what the VB designers were going for. There are many other issues that were missed in VB during its rough opening but execution of their intended theme was pretty good.
Honestly, I love Typhoon Lagoon, but I think the three raft rides Keelhaul Falls, Mayday Falls and Gangplank Falls are the only slides that succeed in 'natural' themeing. The other slides, while nicely hidden in the rock work and are fun rides, truly don't make sense from a themeing standpoint. Why is there fiberglass 'naturally' occurring in the landscape? Those slides should have been made of different material to look like smooth rock if they truly wanted them to be themed in a natural landscape. Same for blizzard beach, melted snow apparently makes fiberglass. Again, fun slides and interesting theme idea and great integration of 'hidden' supports but if you think about it, it just doesn't make sense. Especially from a company that prides itself in the details...
