How long is the ride through the park? If I can only get there an hour before closing is that enough time? Thanks in advance.

It takes roughly an hour to drive around the park.

An hour in advance will be adequate. 15 minutes prior to closing you could probably still get in, as I do not see them turning away a car load of children. I just can not see management turning away anyone who was " in line" at closing time. ( just dont block the driveway)
