You must have hit a bad day. We enjoyed our day there, last year, and found Schlitterbahn to be very unique among waterparks. The greatest improvement that's needed is shade, shade, and more shade. Sitting on the Kansas prairie, you would have thought someone would have done something about that. The other thing might be to put a maximum capacity on admission. Waiting in some of the lines can be a real pain.
This waterpark feels different than others. More of a swimmin' hole atmosphere. Less sterile. More homemade. Less plastic. It just has a different personality.
Granted, Verruckt has been a fiasco since conception. I wouldn't even want to get on the thing.
