I'll second the suggestion to opt out of whale watching. It will take too much time, and it will probably be too dang cold anyway!

Which hotel did you land? If you need them, I can offer some good restaurant suggestions for you.

Since you're flying into/out of Bradley, a trip to Old Sturbridge Village (take I-84 east from Hartford) isn't too far either.

It's a re-creation of a 1830's New England village.

Or while you're at Groton, and wish to visit Boston, you could take Amtrak (rail) from New London, and you'll arrive right in the center of town.

If finances are short and you're willing to use "dormatory" type lodging, there is a hostel within walking distance of the Boston Back Bay station - the first stop your train would make in Boston.

Um, rb_traveler, this thread was started in September 2005; the OP's trip is done.

Not sure why it ws topped/saved. Sometimes, people just want their own ID in a thread so it's easier to search for later.
