Am thinking about using our last day in AC to go to DC for the day. Looked at train and it was about $100 each (me and girlfriend). Not bad but a little more than I would like to spend.Plus we would have to drive to philly for that rate. The greyhound was just $100 for both of us but had some weird time. Only morn.bus leaving at 4:30 am. So I think we are gonna drive. We don't want to put the extra four hundred miles on car so I think we will rent. I saw budget at the airport has cars for $21.99 a day. Guess my question is if this is the best deal? Am I missing any options? Is the airport best place to get car?. Thanks in advance. Will be doing this on thurs. the 14th.
