Is it costly? Well, maybe. But isn't home worth it? I know that as a first year student you don't have a car and not everyone knows an upperclassman with a private vehicle. You could also take Amtrak, I suppose, which I've done but it might not be as convenient for you if your hometown is in Hampton Roads. And do you really want your parents driving all the way to Charlottesville to come get you just to drive back again?
Consider this great service next time you are going home if you live in the state. And if you don't, see if maybe you can catch the train from Union Station in DC to your house (because, you know, the NoVA drop off location is at a Metro stop).
Good luck on finals, everyone!
