I'm going to Wet n Wild this Thursday. The last time I was there about 5 years ago, they had this water ski area, but instead of skis, the motor boat pulled the guests sitting in some kind of inner tube. The boat took 2 passengers at a time, each in their own tube and holding on to their own rope. If I remember correctly, this was an extra charge that was not included in park admission, something like $5. Does anyone know what I am talking about and is it still there?
