Ooh, cheapness. Hmm, there doesn't seem to be a direct overnight train (which would be ideal, 'cause then i could just sleep). The only overnight one in fact, has a 7am-1:005pm layover in DC and gets me to Charlottesville at almost the same time as if i had taken a 5:20am from Boston instead of a 9:45pm. Peter Pan bus service only goes as far as DC, though i could probably get a train from there -- but looking at the schedules, it doesn't seem much of an improvement (11:30pm-10:50am bus, and then there's a 1:50pm train getting me in to Charlottesville at 4pm, which is when the original train options get me in to Charlottesville).
