Actual travel time will be much longer and there's just no way to avoid it no matter the route.The coastal route by car, while somewhat nice and offers some stops, is best viewed from the train, comfortable and you can plan on when you'll arrive. If Acela is out of budget, take the NE Regional which runs more frequently and is still a pretty comfy ride. There's a bar/snack car onboard either train.
If we were talking about getting from BOS to NYC without breaking up the trip to see some sights, Amtrak might make sense -- even for a family of six with luggage. But if the travelers want to stop along the way -- say, in Mystic, New London, and/or New Haven, what are they supposed to do with their luggage? And how easy will it be for them to find a taxi large enough to hold them and their luggage?
Given that the OP is thinking about taking the Cross Sound Ferry from New London to Orient Point, Long Island, a rental vehicle makes a lot of sense.
