New trip coming soon!

OMG....So after more than a year of "no big trips", I finally have a new trip planned. Going to New England in October, 2008.

Itinerary:
Long Beach to NYC
NYC for the night
Rent Car
NYC to Mystic, Connecticut (2 nights)
Connecticut to Providence, Rhode Island (2 nights)
Rhode Island to Brunswick, Maine (1 night)
Maine to Boston, Massachusetts (2 nights)
Boston to Long Beach

Out of all of those states, I've only been to NYC. Any suggestions on places to go while we are in any of these wonderful cities??
