Just a thought...
Until vaccinations get further along there may still be distancing requirements in campgrounds in some states this season. I think the standard in a lot of places has been that camp sites have to be at least 20 feet apart due to Covid. That may reduce the total number spaces available. So it might pay to make your reservations early whether you are a participant staying in a participants-only campground, or a paying customer who camps near a Renfair.
