re: How's My Plan For DC at Christmas?

The walk isn't difficult if you are in even decent shape. Oprah could do it.

While you are walking through though make sure you go up to Arlington House (R.E. Lee/wife's house) for the view back to Lincoln and the Mall. Read up on the history of the place, why union soldiers were buried in the garden, and check out Kennedy's grave.

Also, while walking the Mall make sure you stop at the Korean War Memorial. A lot of people skip it and only go to the Vietnam Wall on the other side of the Mall, but both are worth your time and should be seen.
