If she were actually trying to drive or park in DC proper, I'd say forget the car. It's not worth the trouble. But Marymount is in Arlington, and it's a bit more do-able. The Univ is a bit away from the Ballston Metro stop. I believe they run a shuttle to/from the metro. One of my friends works off Glebe road, and I remember seeing it last month. On another note, if you're a beer guy. Port Brewing in Arlington is freaking awesome! Go to the brewery, their selection there is great. Yeah, I'm a dad also... but my boys are still a bit away from college.
