From Boston Logan Airport, you can take a water taxi to the Marriott Long Wharf. There are several companies that offer water taxi services, with varying prices.
The one Annie and Ryan have used is the yellow-and-blue Water Bus through the Boston Harbor City Cruises, which ran $15 per person one-way.
Another option for getting from Logan Airport to the Marriott Long Wharf is to take a short bus ride on the free MassPort shuttle bus to the Blue Line on the T (Airport station). Take the Blue Line toward Bowdoin and get off after 2 stops at Aquarium.
The T costs $2.60 one way and runs about every 10 minutes. [ Learn more here ]

The MBTA public transit subway system (the "T") is safe and reliable.
