I thought this was a great way to quickly get from Boston to Provincetown, and I'm really glad I did it. It was super easy - you get on the T at the Boston airport, get off at the Aquarium station 2 stops later, and the wharf where the boat departs is right there. Then it lets you off right in the middle of Provincetown, on the pier that's an easy walk to Commercial Street shops and dining. Well worth the price (which I admit I found a little steep when I first heard about this but it's worth it for the speed and convenience and not having to deal with traffic). Beautiful views of the water. You can sit on several outdoor decks in the sun (there didn't seem to be too many shaded seats outdoors), or inside in a booth or in seats like what you'd find in a movie theater. Bring a sweater as it gets VERY windy and chilly on the outdoor decks even on a hot day and they crank the AC on the indoor decks.
