Totally different and very fun. Though it was a little tight for 10 people (4 children, 6 adults), we had a great time. I would do it again. Location is great- walking distance to everything in the center of Boston. We didn't need our cars the entire time we were there. And our host was friendly and present throughout the stay though we did not need anything. I was worried we may have taxed the waste tank by the end of the third day, and the vague smell from the downstairs toilet scared me, but we had no issues while on board. Great way to do Boston!
