$30/ night seems like a decent deal for a place like that. NJ state parks are $25/night for non-residents like myself.
You should see what some places are changing in the east. I was planning a tour in 2021. One place in nowhere special NY state wanted over $100/night. I thought there was something wrong with my computer at first. I went off route a few miles and got a better deal but still paid something like $45 with a cash discount.
