This is the schedule for my 2-day visit to Washington D.C. On the first day, we arrive at Reagan Airport at 6. 00 A.M, take a cab to hotel nearby. After checking in, we go to the White House and take some pictures. At about 10. 00, we visit the Capitol. After lunch, we visit the Washington National Cathedral and spend the rest of the day visiting National History Museum.

On the second day, we go to National Gallery of Art. We have lunch at the American Indian Museum Restaurant. In the afternoon we go to Washington Monument and American History Museum.

I hope I enjoy my time in this city.
