Getting to D.C. from the Philly area

PJLaur

This is in reference to the D.C. solo show, of course. Amtrak is a lot more expensive than I anticipated. Almost $200 for a roundtrip. I could get $88 for round trip if I want to arrive in D.C. at 2:30am, um, no.

I'm trying to look at buses, but no luck.

How is everyone else getting there? Driving?
