Just in time for the Boston AGO Convention, a new Logan Airport-Back Bay Shuttle has begun service at all four airport terminals. It runs every 20 minutes from 6:00 am to 9:00 pm, costs $5, and brings travelers from the airport to Copley Square, a short walk from the Marriott. (It also stops at Hynes Convention Center, so be sure you get off at Copley Square.) Travel time in normal traffic is 30-45 minutes. More information is at: http://www.flylogan.com Please note that payment is by credit card only. Cash is not accepted.
On the curb outside baggage claim at the airport, follow signs to “Logan Express.” There are several Logan Express buses to various destinations; the one you want is clearly marked “Back Bay.” When the bus lets you off at Copley Square, Trinity Church will be at your back and Boston Public Library will be directly ahead. Take Huntington Ave. (to the right of the Westin Hotel sign) and continue straight ahead two blocks to the Marriott Copley. This walk takes 10 minutes at most.
