"Telling somebody they have to find some remote place to boondock because they want to get out and have a relaxing weekend seems a little pushy."
I don't think the OP was complaining that the neighbours were running a generator, but that they were inconsiderate. No one should be running a noisy "construction" generator in any campground, as that is simply rude.
If they are too cheap to buy a proper generator, so as to not bother others excessively, it is they who should be camping somewhere else, JMO.
We are all out to
, and most people are very considerate.
