Kids under 10 are FREE and they do charge 7.50 per person
They charge per person in the car. But I believe kids under 11 is free.
I believe you pay per vehicle not per person
I didn't take kids, but they do let a certain age and under get in free. I don't know the age though.
Im not really sure if its free for children. We didnt have any kids with us so i didnt notice
