We went to Washington D.C. during Spring Break last year (April 2010). We had the best experiences. We took public transportation (either subway or bus) to see all the sights. We went to Mount Vernon, Smithsonian, National Archives, toured the inside of The Capitol building, Washington Monument, Lincoln Memorial, and Georgetown...just to name a few places we visited. The Cherry blossoms were in full bloom because the weather was unusually warm during our visit. We were told that not many visitors are able to catch the cherry blossom during their full bloom and we were among the lucky ones!

Best of all, it was an educational trip for our daughter also. She was studying American government at school and she was able to see a lot of the places that was discussed in class.
