We will be visiting DC first of April 2013. We have chosen to stay in Arlington due to rave reviews of locals, history, and more economicsl. I have narrowed down to 3 hotels: Econo Lodge Metro, Americana, and BW Rossyln/Iwo Jima. Which would be considered more safe for night walks back from metro and distance? Any have activities within walking distance for evening? The BW is on list due to indoor pool in case there is no activities for daughter (10 yrs) at night but perhaps not needed. We are going into this blind (although have spent hours researching!) thank you so very much!
