That's a weird itinerary because it jumps from Mystic, CT to Maine. Lots in between there!
* Newport, RI?
* Stop and see the rock at Plymouth (it's anticlimactic, but you can do it in 30 minutes and say you saw it. It's especially not-gorgeous at low tide, so try to time it for that.)
* Boston, MA? There's a couple things worth seeing there.
* Portland, ME is supposed to have INCREDIBLE foodie restaurants
