If I wanted to stay somewhere where all I could hear was other people's noise, I'd camp at a shopping mall on black Friday, or a construction site, or in a traffic jam, or at a major sporting event, or in a subway station, a NASCAR race, an airport runway, or maybe even a rock concert.
I don't know anyone who asks, "when is -your preferred campground here- the busiest, I love crowds, and screaming kids, and loud generators, and barking dogs, and TVs and stereos blaring?". (actually, I like dogs, just not barking ones late at night :C ).
