Hi Kiteri
If you are interested in coming to the Kittery area, I would suggest a campground on or near the seacoast. I'm guessing the kids would enjoy the beaches, as you probably would as well. Even tho some of those campgrounds are near us, we've never been to them. I would suggest the Maine ones over the NH ones though. And maybe other campers on this forum would be interested in a seacoast visit?!?
