By the 'T'—There are three reasonably close subway stops: Hynes/ICA on the B, C and D branches of the Green Line, Prudential Center on the E branch of the Green Line, and Back Bay on the Orange Line. Which stop is best for you probably depends on where you are coming from and whether you mind walking outdoors. Hynes/ ICA involves a slightly longer walk outside but has more frequent service and better connections.

See or call 617-222-3200 or 1-800-392-6100.

These are about the same distance to the convention (and about the same difficulty — the mall has maps everywhere).
