Washington, D.C., the capital of the USA, is a beautiful and interesting city.  It is filled with numerous monuments, museums, and public parks including the White House, the US Capitol, and many other government buildings.  There are plenty of interesting things to see in Washington and most of them are completely free.  Washington has a diverse population and a great variety of ethnic restaurants.  It is only an hour drive to the port city of Baltimore, and a half-day drive to New York City. 

Be advised that the District of Columbia, where Washington is located, is wedged tightly between the states of Maryland and Virginia.  The district is ringed by the Potomac River, which serves as the demarcation line.  It is very easy to go from D.C. to Virginia and Maryland and back again in one taxi ride, often without even knowing it.  Please check a map of the area before you travel in order to establish a visual image of where D.C. is, and how it relates to both Maryland and Virginia.

The Metro System (underground and above ground rail) is efficient, clean, and reasonably priced.  Most D.C. residents use the Metro System daily, because traffic is often very congested on the D.C. highways and surface streets.  Parking spaces are scarce and paid parking is expensive.  Plan to use The Metro during your stay.  There is a station that brings you above ground in the lobby of the Grand Hyatt Washington Hotel, where the congress is being held.
