I recently went to the park (June 30). I was able to see their new Zip Line and water maze. The water maze looked like it would be a lot of fun. Lots of water can be sent in many places to get you wet, and there is even two water guns on a viewing platform above the maze so viewers can squirt water at people in the maze.
I didn't get to try it. I only had 3 hours in the water park and I used up all that time photographing the park for a website I own.
As for the zipline:
I don't know what the price was originally, but I don't know if I'd want to pay a certain fee to do this either. No offence, just my opinion.
Edit: Just read through a few pages back and noticed that you people are looking for a trip report. If you can give me time, I can write one up of my visit on June 30th. It'll include the POV's I shot of the slides, which I received full written permission from management to so.
So long, and thanks for all the fish!
