YOu'll be staying elsewhere, then....

But, why are you getting a car, anyway? Take the T or a cab to the wedding. If you need a car for the latter part of your trip, pick it up after the wedding.

Enjoy Boston, car free.

I love the SHeraton BOston. THey always treat me well.

Oh, and if you're "just crashing", have you checked out the Westin on the waterfront? It's usually cheap on the weekends, and it's a bit closer to the Marriott Long Warf. Still, no car necessary. SOmeone else can better advise, but I think you can take the water shuttle from the airport and then a short cab ride to the hotel.
