Campground recommendations in southern NH Options

[NHCamper]

I am looking for any recommendations for campgrounds in central to southern NH that would be good for a family. We like a quiet campground with large sites and with some basic amenities -- playground, pool, etc. A lake would be a real plus. Ocean is OK but they are usually cramped, crowded and noisy. We don't want to camp with partiers, drunks, and all nighters!! Has anyone stayed at Barrington Shores in Barrington, NH. It looks somewhat promising in their website. Any suggestions would be appreciated. Thank you.
