I have spent a fair amount of time in NE in the summers (and in the winters). A few thoughts:
Rockland/Camden areas are very nice, but a long-ass haul from NYC and even Boston. Maine is big, and all but the southernmost parts take a long time to get to. Traffic can be pretty rough on summer weekends, and you will spend a lot of time in the car getting to your destination no matter what highway you take
It is cold in NE. I have been in Maine in July when it was too cold to sit comfortably on the beach. Late July/August is your best bet.
Other areas you might consider:
Finger Lakes region (though IMO the sights worth seeing are kind of few and far between - a nice getaway for adults if you just want peace and quiet and R&R, but not a whole lot to do besides that)
Take a look at Quechee/Woodstock, VT/Hanover, NH area (Hanover is where Dartmouth is). We have made a few fun trips there over the years. Great area for golfing if you're into that
I was in Ludlow, VT last summer and enjoyed it. A bit out of the way. There are lots of ski resorts that change over to golfing/outdoorsy-type resorts in the summer - great for kids
Cape Cod is also excellent. Great food, nice little towns to browse around in, etc. The beaches suck, but if you're not into swimming in the ocean/walking on the beach/sea-shell hunting, etc., it won't matter
