Maine has a bunch to offer and what you get depends on what you enjoy and where you go. If your stops are places like Wells, Ogunquit, Freeport, Camden, and Bar Harbor you'll see the tourist side. Mainers tend to avoid those places like the plague once tourists arrive. The coast has over 3500 miles of shoreline, and the river systems/forest access were the population draws that brought people here. Most communities do not have dozens of restaurants, gift shops, movie theaters, and outlet stores.
Tidal range differs in the river systems and shoreline, from single digit ranges in York, to over twenty foot swings Downeast. Quoddy Head would put you to the Easternmost point and offers incredible views. The harbors in Cutler, Jonesport and Deer Isle/Stonington are real working waterfronts with a rainbow of commercial vessels decorating the harbors.
If you do end up in Freeport the LL Bean store is interesting, Bucks Naked BBQ is delicious, and the Maine Beer Company is knocking it out of the park there. My sister lives there, so I'll endure that.
Besides lobster, theres haddock, clams, halibut and scallops that will be fresh. Fish and clam chowder, lobster stew... Can't forget the strawberries, blueberries and apples. Probably ought to have a potato, or at least some humpty dumpty BBQ chips. Besides Moxie, we also have Allens Coffee Brandy, which is a regional thing.
Cadillac Mountain, Mount Katahdin... gem mining in western Maine... the Desert of Maine... the Downeaster railway... whitewater rafting the Penobscot, Dead or Kennebec rivers...
