We have stayed at Embassy Suites across the street from I think it is King Station in Alexandria. Without having to change trains we easily made it to many tourist places. I made advanced reservation tickets for both the Holocaust Museum and African American Museum and found them both to be wonderfully done. I would look at your state senate/rep sites to see what tickets they may be able to help with. The last time I went I was unable to get tickets to the Washington Monument. There are so many free things to do but I did pay for the spy museum and a night time monument tour. We did not plan where to eat ahead of time and ate where/wehn we were hungry including Old Town Alexandria and our hotel so I can't answer those questions.
