Stacy L asked:


We’re thinking of flying to Baltimore, spending a day, then going to Washington DC for a few days. We’ll be traveling with our 6-month old daughter, and I’m trying to figure out what would be the best way to travel from Baltimore to DC with luggage and a baby. Any suggestions?

I am looking to travel to both Washington DC for a night then to Baltimore Maryland. I was planning on flying and not renting a car, so I was wondering what the best way to get from Washinton DC to downtown Baltimore was on a weekend. I notice MARC does not operate on the weekends. Any suggestions would be greatly appreciated!
