For ages over 3, a single admission ticket is $58 at the door, $39 if you purchase online, or $35 when you purchase four or more tickets (also online). Groupon currently also has a deal on 4 tickets for $116.
Checkout their website because ticket prices vary by age. There is also a parking fee. I have used Groupon deals and found coupons in local magazines too.
I believe its about $59 or $60, but its cheaper if you get the annual pass.
