Ok, at $20 per campsite per day, that's $400 for all five sites for Friday, Saturday, Sunday, and Monday evenings. Divided by 15 people, that's just under $27 per person.
That's so not a problem.
Also, it would be perfect to keep the fifth site in the middle, because we can make that the evening communal firepit/gathering place with less worry of disturbing our neighbors. The bear box would also make a great place for the bar needs.
