When I debated driving vs. Amtrak, I realized that my daughter would be coming home for the summer in a couple of weeks, no car, and she sublets her room over the summer so we needed to take back a lot of her stuff. The overnight in Boston was a stop before we headed to Gloucester for a wedding, so we would’ve also had to rent a car. I will book early for her graduation next May. Her Ubers from back bay have always been under $20 (I pay for transportation to and from school, she pays for the day to day in Boston).
