Should you be so fortunate as to find yourself in Mystic Connecticut, the town is well worth seeing, and don't miss Old Mystic Seaport. Old Mystic Village is a glorified strip mall, worth a visit, only if you need something.
I have stayed at the Wayside Inn, in South Sudbury, Massachussetts. It's lovely. It was built in the eighteenth century, and much of the period feel is still there, though not in the bathrooms.
Salem Massachussetts has a lot of witchy stuff for the tourists, but they also have The Flying Cloud, that has the record for the fastest voyage around Cape Horn, and is famed in song, story, and a Wedgewood China pattern.
