One certain campground I enjoy staying in often just takes my name and the size of my RV, never a cc number. Knowing how people forget, I usually try and remember to call a few days before arrival just to make sure. Lo and behold a time or two theyy didn't even remember we had reservations. Once I inquired about giving a number and was told "sure" and there were no problems upon arrival on that particular trip. The last time, I made a reservation that was as you described, with no Cc number to hold the site. I later had to call and cancel and they couldn't even find my reservation! I know this going in, so I try to stay on top of it, but as you know it certainly is not a good way to go about taking reservations for a campsite.
