D.C. is friendly and it is very easy to get around on the Metro. Metro is clean and safe. Protect your Metrorail farecard; ours seemed to get demagnetized easily and the Metro official at Metro Center wasn't very helpful. When researching restaurants you should try to determine if they are in office buildings and understand they probably won't be open on the weekends. We could not find a bar in Dupont Circle. Man, has that place changed in 15 years.
