Don't let the size of the building stop you from going here. They have a gift shop in the front of the building with all kinds of presidential stuff. The self guided tour includes a 70-minute video of the inception and reconstruction of the US whitehouse. There is an amazing whitehouse replica inside the museum detailing everything right down to the books on the shelves. The back of the piece is open to show in detail the layout of the entire structure including furnature. There are diaramas of the oval office of many presidents showing how they each had it decorated. You can even sit behind the desk of the president for a photo op. Bring your camera!
