Anyway, one thing that can be done well in a day is a tour of the Capitol Building, although you can learn from our mistakes. First, they allow no food or drink inside the building AT ALL, and unlike many of the museums and other places there are no lockers or coat check available. You can get around this problem by planning ahead and leaving your pack in lockers at one of the museums, but they are a good long walk away. We had morning tour reservations and lunch packed along because food in DC is crazy expensive ($6.25 for a McDonald's burger), so we left to do other things and eat then returned for a later tour. Thankfully you don't need an advance reservation this time of year.
My general assessment of the Capitol Building is that it is much more lovely from the outside and the tour mainly seems to focus on the architecture of the Rotunda plus the statuary below. There are way cooler things to do inside, like watch legislation being made. We did that, it was super geeky fun, and we will share it in our next post.
