If you look at the campsite map, the dog area was by campsite c. looks like there's some private tent sites, with parking the same as the group sites, so maybe if there's enough people to fill the group sites, those with dogs could camp nearby in the tent sites, we're all going to park in the same place anyway. However, if we could tell them we already had pets booked, and needed C, maybe they would hook us up.
If I can come I have a mattress inflator, that has it's own battery. I'll bring that, or for $8 at Walmart, you can have one yourself. Charge has taken me through 3 weeks of camping, moving every few days, still had plenty of charge when I got home, have had it for 5 years. Also had 1 that ran off the cigarette lighter, but it wasn't good for walk in sites, and didn't hold up as long, though it was lighter..
