Will be in DC 2 days next week. Staying at the Omni Shoreham hotel in the zoo area. There is a Metro stop right by the hotel.
Plan to visit the National Portrait Gallery, Bureau of Engraving, Library of Congress, Patent Office, International Spy Museum and National Museum of The American Indian.
Can we easily visit the above attractions with our rental car or would we be better off using the Metro? If we use the car will parking fees be excessive?
