從機場Terminal B到Grenn Line的Hynes/ICA - 波士頓

要怎麼從機場Terminal B到 Grenn Line的 Hynes/ICA?

Take free shuttle service to Airport T subway station.
Take blue line train downtown to Government Center station
and transfer to green line.
Take westbound B, C, or D train to Hynes Convention Center stop.

這是我查到的方式, 想問
1. 這樣有行李方便上下車嗎?
2. free shuttle service 幾點開始有?

麻煩熱心的大家幫幫忙喔..
