I went with my brother who is an avid astronomy buff. Definitely an all day attraction as there are quite a few exhibits. On the day we went, there were astronomers from local universities talking with visitors so we had a nice opportunity to hear all about their work. If you are interested in astronomy at all then I recommend this museum. I learned quite a bit from the exhibits. I would recommend eating before you go inside because the food is overpriced, just like every other museum I've been to. The view, however, is spectacular and after you leave the planetarium I would recommend walking along the lake and enjoying the cool breeze and wonderful view.
