2. Memorials: If you are not American, you may want to give these a skip. If you are, you should try and see as many as possible. Although, to be honest, they are a bit spread out. I suggest that you take a guided tour to see all of them within the 96 hours that you have. These guides will also throw out a few interesting facts. This includes the Washington Monument, Lincoln Memorial, Vietnam, Jefferson Memorial and the World War II memorial.
