As the thread title says I'm visiting DC this summer with my mother as part of my graduation 'party'. I know we have a couple people here from around DC and plenty of people who have been to DC so do you guys have any reccomendations on what I should visit (and approximately how much time I should expect to spend in different areas)? Also, for those who know DC fairly well, any areas I should avoid when getting a hotel? I would like to clarify that we won't have access to a car. Bus and rail is all that is available to me.
