If you look at the
Washington DC page you will see a list of suggestions on places to visit in the city. The
Family Vacation page is particularly helpful.
For historical and educational sites i would recommend a visit to the
National Museum of Natural History, the
National Museum of American History and the
International Spy Museum.
If you are looking for a good room rate you can check out the
discount hotels which DC has to offer and hopefully you will find something to suit your families needs.
