You can find parking for anywhere from $5-$20 a car depending on where you park. But $12 per person 11+ military and 65+ $8 per person. 10 and under are free. There are also options for rides as well.
$20/car for parking, entrance is $12/person, kids under 10 are free. There's also a different cost for the elderly, but I don't remember what it is.
