The shuttle requires waiting outside in Boston weather for howsoever long it takes to pick you up, then hauling your luggage onto the shuttle, getting it stowed, taking a ride etc. etc. third-world experience w/o the charm. The Silver Line is great, but once again, assuming you’re not downtown already, you need to fight your way across/up and down South Station, usually during a busy time, and hoist all of your luggage onto a bus. How is any of the above superior to a cab, assuming that you’re willing to pay? Compare with Zurich. Or Denver, even. Places where the train goes right. to. the. airport.
