I am happy with a 3* or better, the goal is the least expensive. Happy to stay as far out as Arlington & Crystal city, especially since we are only tehre for 2 full days (take early train on 4th day). Considering we will arrive at DCA late on the 13th, is Crystal city a good option? Yes i have been researching for a while, but since i am only a month away now i am definately ready to commit to this leg of the trip. Thanks for your help.
