I've read the forums but need some advice. I'm travelling to D.C. with husband and two teenagers for 2 nights (March 21 & 22). Is Dupont Circle, Foggey Bottom or Dupont Circle the best place to stay. We want to see the monuments, spend some time at the Smithsonian and maybe the capitol. We will not have a rental car. Budget is $300 or less per night. Any suggestions or guidance to narrow this down is appreciated.
