We had the day off, and decided to take in the Museum and IMAX. From the start, the parking is so convenient (and free if you buy IMAX tickets), and the lady at the counter was very helpful (Erica?) I got in free because I teach at a private boarding high school and had two of my students along. It was a weekday and we almost had the place to ourselves. Very interesting and informative. I liked the interactive stuff. I'd go again, because right now they have the Lincoln exhibit and the Lincoln film on big screen at the IMAX.
