Blair's favorite recommendation is to visit the National Mall at night. The lights on the monuments are breathtaking.
Jeni's favorite greenhouse. A must-visit to escape the cold.
An absolute must-see if you haven't. The cherry blossoms should be at the end of their bloom during the wedding weekend. Go early Saturday morning to avoid the crowds.
Wonderful park to walk around in NW DC. Jeni and Blair would take the cats on walks here.
