You can have as many in a car as you'd like. It's $9/ person 12 and up, $4 for ages 4-11 and free for 3 and younger
Everything Kyle said is correct. I would add that you need to bring cash.
On a side note. The concession stand has all the goodies you could need. Perk, is you can bring your own food as well. Just no alcohol.
You can have as many in your car as you can safely fit. They charge by the person, not a flat rate per car. All admissions are in cash.
