Hi there, Washington DC is really an amazing place and if you visit memorials such as the Lincoln Memorial and the Vietnam Veterans Memorial at night, you will be even more amazed at how beautiful they really are. A great way to enjoy Washington attractions is by paddle boat or a dinner cruise on the Potomac River. Also, you can visit the grand Union Station and the adjacent US Capitol, the Kennedy Center, the White House and Freedom Park. Hope this helps VacationBuddy
