It's free to get in, but if you want to do any rides it's 1$ per ticket. Once you get up to 100 tickets, it's 75$. The rides are 5 - 10 tickets each. If they offer you a wristband take that instead though. I believe it's 25$ without the spring break special, and it's worth the money. It gives you unlimited outdoor activities, including go karts and mini-golf.
Best bet is Groupon passes. They were 25 i think for unlimited rides and a souvenir cup.
