There's no cover charge to get in. You pay per ride and the tickets are about 10 rides for $45, 5 for $25 or around $6 if buy single ticket price range if you buy tickets there. They also have 2 hour passes you can by there and on groupon , I don't remember those prices tho.
Use groupon. They have a good deal.
No admission price. You pay per ride or can get a wristband for various amounts of time. Those are the best deal.
