The bride and I were just there. Had a wonderful time, even extended the stay by a day. Shot an approach into IWI last Tuesday am, stayed until Saturday AM. Lodged at the Rocktide Inn in Boothbay Harbor. Nice quiet little inn right on the harbor. Chose it because it has a three day cancellation policy, rather than the 14 days required by most. Rented a car (Enterprise delivered it to the FBO, and we returned it the same way) and drove up to Rockland. Not our cup of tea, but loved the back roads from just north of Pemaquid down to Southport. The Botanical garden was first rate, and I'm not really much for that sort of thing. Went sea kayaking, whale watching (in a dense fog, but it was fun anyway), and ate lobster every different way we could order it.
Weather was not really conducive to doing a lot of flying during our stay, but the flight home was ceiling unlimited and vis. 100 miles. Could see from the coast all the way to the mountains.
Great fun, great people up there. We'll be back.
