Never reach this place without a reservation. People there are really hostile if you do that. Differently from many other campgrounds we've stayed in the US, which show the guests the open spots in the office for you to choose when you arrive late, they don't allow late check ins. We've stayed overnight as an emergency measure, because we had an issue with the RV and there was no other place to go and we have been treated as trash the other day, when we came to the office for paying our stay (which was very expensive BTW). That's completely nonsense, as there were lots of empty spots for parking the RV.
