Connecticut coast - sites to see, places to stay

And, of course, I forgot one....
If any interest, there is the Submarine Museum in Groton (east side of the river from New London. A lot of history there including the Nautilus. I did take my son there years ago.
And another I almost totally forgot.
There is a museum at the US Coast Guard Academy. I know it is small because I was friends with those that assembled it, but I have never been there.
