Too many kids, too little space
With the exception of a handful of the sites at this campground (mainly, the ones on the pond that go exceptionally quickly), the sites are too small, too close together, and there are a ton of kids. From my site, I could hear our neighbors blasting their radio all day (even after quiet hours), and another group of people somewhere further away singing pretty much all night.
The pluses are it's relatively close to Boston and Worcester if you need a day or two away (and can book one of the quieter sites), the bathrooms and showers are clean (and free), and the rangers are exceptionally friendly.
