Do we need to buy tickets online or can we purchase once we arrive?? Is it 35 per person or per car???

You can do any of the two, online or at the entrance.

Prime days are $45 dollars and non prime days are $35, its per car.

You can buy tickets when you arrive. You can use cash or credit card. Don't know about purchasing them online. Depending on which day of the week you go, the charge is either 35 or 45 dollars.

You can buy the tickets online on or once you arrive
