If the Field Museum is too crowded or you want to try something new, head to the Museum of Science and Industry. Get there early if you want to see any of the special exhibits because it seems like they sell out quickly. The museum is huge, though, and when we got there around 2:00 pm it was perfectly crowded. There are a lot of fun exhibits for people of all ages (from toddler to adult). Also a discount for IL residents.
