Summer in New England - what are my options?

[LMUMegan]

If I want to cruise New England in the summer months am I limited to Cunard and Carnival? I would love to travel in the fall, but DH is a teacher so his schedule doesn't allow it. Any thoughts on either of these lines for their New England cruise?

There is Holland America. The Maasdam goes back and forth from Montreal to Boston in June and again in August, with a break in July to head to Europe.

 

Looks like RCCL also plies those waters.
