Hi folks,
While this is by no means comprehensive, this is my "local knowledge" of some of the camping and lodging options listed....
The closest lodging place is the Westwinds B & B
From there, your next closest options are the Hancock Inn
(http://www.greenfieldinn.com/), which are both a bit shwanky, but nice if you like that kind of thing...(quite the opposite of a camp cabin!) I wouldn't expect kid friendly, though.
And there's always the lovely Inn at Crotched Mountain, whose owners I have known for many years. There is a great view and a pool. It's a very nice place...
I have heard from some friends who stayed there that the Peterborough Manor is really cool
The Herban Living B & B is owned by some friends of mine, who also operate one of the region's Community Supported Agriculture farms - all organic...
As to the local camping, your closest choices are Greenfield State Park and Seven Maples. The first is a pretty big state park, with a nice lake and canoe and kayak rentals. The Seven Maples is more cozy - "family camping"...
That's about all I know...
Don't hesitate to call if you have any questions...603-588-6239
