Aside from the White House, the United States Capitol building is the most visited building in Washington. This incredible building with its regal dome and classic architecture symbolizes democracy to everyone who sees it. The view from the front steps is like nothing else, so make sure you have your camera with you. Tours are available at the kiosk on the southwest side of the Capitol, and are free of charge, on a first-come, first-served basis. Plan to get there early, as there are always plenty of people in line for this extremely popular attraction.
Lots of wide eyes sit in the auditorium that screens some very crowd-pleasing, family friendly fare. When you take the kids to visit the National Air and Space Museum, make sure you leave enough time to enjoy some cinematic flight in this excellent IMAX outlet.
H Street Country Club offers an average golfing experience but includes a bit of built-in challenges. The course itself isn't quite evenly maintained and there is the issue of airplane noise due to its location, but overall it offers nice views of the city and the staff is friendly. Another amenity is the great menu at the concession, so either before or after your tee time, you can enjoy a hearty meal.
The two of you deserve to put some artistic flair into your romantic time together, and there's no better place to do that than the John F. Kennedy Center for the Performing Arts. America's memorial to President Kennedy keeps an artistic tradition alive that would have put a smile on the face of the beloved fallen leader. There are 7 different theaters in the venue that are always featuring such works as ballet, dance, opera, symphonic presentations and so much more. There are enough places on the grounds for the two of you to sit and enjoy each other's company before or after whatever production you have decided to take in.
