We went to this show in our 37 Chevy coupe...460 miles. It was a good show and the Gilmore Museum is a great place to have it. A wonderful car museum for all in attendance to see.
If you are a camper then you can stay right there at the museum. That is what I always do and they have bands there the night before also. As for hotels, I don't know.
The Gilmore has a link with all the hotels in the area. https://reservations.arestravel.com/hotel/list/14695/m3921
