I have to admit, this seems more "Six Flags" than "Holiday World" to me. I'd certainly ride it next time I go, but it seems a bit gimmicky and overblown. It's also a bit surprising given the Perilous Plunge and Raven incidents to see them go with something like this.
It gives me another reason to venture out to the park. It looks freaking amazing. Elevator looks scary as hell, wall of water hitting you will be awesome. Can you imagine being in the splash zone for this? Also, being able to enter from HW or Splashing Safari is a great idea! Plus it gives the park an icon.
