Unfortunately the festival grounds aren't within walking distance of an area that has bars/restaurants (and if there were, the owners of those places would probably charge money to use the toilets).
Yeah, I don't think camping will work for Jim and I. It's not that I fear porta-potties, it's just. Well, Jim's health is still not up to par and the porta-potty situation... erm, that won't be good for anyone. I'm so sorry, I hate to be a pain in the butt!! No pun intended. Please don't hold back from doing what you all think is best in terms of lodging and finances. If camping is the way to go, then by all mean - go for it!
