I will be spending a few days in Washington, DC later this month, and I plan to see and do alot in the city, but I was also wanting to be able to hop onto one of those Amtrak trains to Baltimore for a day excursion.
I must confess that I have never travelled Amtrak before, so I'm a bit uncertain whether I need to order my tickets in advance, or if it will be possible to buy at the station upon arrival. I would love to be able to "wing" it, and not commit myself to a certain hour to leave Washington for Baltimore, and vice-versa.
However, if this would be an exceedingly risky thing to wait til the last minute, I'll order in advance. Any advice would be most appreciated! Thanks!
