What I like about the waterpark is that the theming doesn't stop in there. I can't tell much about it, but there are some slides and what looks like a wave pool. There is also a short climbing wall in the picture I've posted here (left), and a cluster of birdhouses - which is an unusual choice of decor, and you definitely aren't inviting live birds to fly through.
Off to the right is a more colorful building that, apparently, is the boardwalk/shopping building that is accessed from outside the theme park. It is attractive enough and is embellished with modern lighting and park-like seating areas for folks to enjoy. It looks like there are some water features, as well.
