Washington, DC is teeming with things to do, which makes it a great place to bring along your spouse, gf/bf, kids, friends, parents, and well wishers - they certainly won't be bored. The National Mall is an excellent place to fly a kite while seeing the national monuments, the Capitol Building, and the White House. The Smithsonian museums that line the Mall have amazing and varied collections and all are free. The city is packed with small art galleries with unique local and international exhibits. The National Zoo (also free to enter) is right off the metro and boasts two pandas, a few tiger cubs, and all the traditional zoo animals. And you can go say hi to the new President, or at least his security detail.
