The subject at hand being the spot being reserved, not how he makes his living or makes vids, I'd be looking for some compensation in some way. Like a free stay at a future date. Failing that satisfaction, I'd be temped to drive there bright and early and set up my camper before the rest get there, with my confirmation in hand. Thats a poor way to treat customers who have reserved a site. Lock in fee? Maybe for a specific site instead of a site they designate, but my confirmed reservation and accepted fee ARE my lock in to stay there one way or another. I'm thinking Id set up right next to their main office and see if that suits them.
