I have been to Arlington national Cemetery several times and it is absolutely a must see. I did take the ANC shuttle tour because I was traveling with family members who could not walk very far, but I think that next time I will explore on foot with a guide book. Unfortunately the guide on this "tour" although very friendly, did not give that much useful or interesting information. I just looked at it as getting a ride around the cemetery if it is difficult for you to walk. I noticed that a lot of people were not getting off the shuttle at Arlington House. Part of the problem may also be because the staff on the tour did not give a good description of what was there. I do recommend making a stop here even if the house is closed. It offered a beautiful view of Washington DC. It also overlooks the Kenedy's grave site. Pierre Charles L'Enfant's gave site is also here, overlooking the city. There is also a beautiful garden that you can visit.
