Didn't actually go in. They charge $11 per person or $28 per car. It was a little rich for us because we were just passing through and didn't care to walk through the exhibits. Looks like a nice park if you are interested in all it has to offer!
It's an ok stop. It was probably a lot nicer 10-20 years ago. A lot of it has fallen into disrepair. They do give you an old tape recorder to carry around to explain the different buildings. The staff was very friendly and knowledgable. The gift shop had some antiques for sale.
Only open 9-5 Thursday-Saturday
Very nice updated and clean. Pricey for a campground but reasonable for a resort. $55 per night with hookups. There is a train track right on the other side of the trees, so if that bothers you don't stay here. Other than that highly satisfied with our stay!
I'm not really a car lover but I love history and my husband really liked the motorcycles. $10 per adult is a fair price for this attraction.
