I´m from Guatemala, and I´ve been in Washingt and I´d Loved it. I will be the 4th week of November, with my teen kids. It´s too easy and fast to move in the city walking or by the meter. To visit the Smithsonian Museums, you have to be sure which one you want to visit, because in the biggest ones like the Space Museum, or the Natural History ´cause you need almost a whole day: you can almost visit Baltimore using AMTRAK , Georgetown(the cost is not more than US$12.00 if you are in the downtown, I´d been in the Gran Hyatt because it was a working meeting but we also stayed at the Red Roof Hotel in the Chinatown area, is a good hotel, clean, no luxury and cheap and in a very good location. We´ll be in the same hotel again. Through Hoteles.com I´ll get 7 days for US$700.00, for 3 persons.
