I’m comfortable with the Airbnb style online only service concept. On the website you “agree” to pay the $5 reservation fee, but you are allowed to waive it at a later step; for example because you have already arrived. You can imagine my disappointment after entering the discount code for Passport America and finding it doesn’t work. The price is double what it should be. Some places state up front that the rate is only accepted for one night. It’s possible this place does that and simply doesn’t tell you that and there is no way to find out since you can’t talk to anyone. The phone number provides the message that it’s online only and does not take messages. I left in frustration although perhaps I should have stayed until such time as someone arrived to take the proper payment in person. Perhaps you receive the Wi-Fi password with the confirmation email, but I wouldn’t trust it given the lack of forethought with the rest of this online setup.
The park is basically a field with utility connections. Be cautious about driving through to a spot because you could run over a sewer hookup in the grass. They aren’t marked and somewhat difficult to see. It would be pretty tight accommodations if full, but there were only 3 occupied sites when I drove through midweek.
