This isn't a road trip question as such more a tail end of a road trip question! We will be flying back from Palm Springs to DC after a 3 week East to West Road Trip and we have a two day window to explore DC. We have not been before. We will not have a car as this is being dropped in Palm Springs the day before. My question is ... where can we stay that is cheap, safe and most of all accessible to the main areas on DC? We fly in to Reagan on the 28th and out of Dulles on the 30th August 2012.
