I've been to Maine only once, and it was early summertime. I visited a friend who was living in York Beach. It was kinda like a cape codfamily community, not too crowded, and right around the corner from Kennebunkport. Needless to say, I went there about 15 years ago, long before Kennebunkport became well known. I don't know how much it's changed since then. It may be much more expensive. But it was charming. Very New England. A lot like parts of the cape.
And I've never been to Ogunquit, but will go soon, I'm sure.
Have you considered Acadia? Again, I've never been, but will make it a point to one day soon.
Last summer, we spent a weekend in Woodstock, VT. It was such a charming little town, with lots of summer activities, shopping, etc. Unfortunately, a few of the restaurants were closed for the season. There's a lot of hiking around there, the Simon Pearce glassblowing factory is up there, and there's lots of handmade pottery, ma and pa shops, covered bridges, etc. I wish I could live up there...
