Great free science museum, a gem for St. Louis, along with the Zoo and other museums.
Yes, you have to pay for special exhibits and shows, and the parking can cost money but it can also be free if you find a place to park in Forrest Park on the Planetarium side.
And there's still SO much for adults and children to see and explore without spending a dime.
Membership is a great value too. Even if you only visit once, it can still save you money with free parking, and tickets to the Discovery Room (best for younger children and toddlers), Omnimax, and Planetarium shows. AND it'll reciprocate at other science museums across the country. I've used mine at the Field Museum and Science & Industry in Chicago, and those are between $20-30 a person just to get in, but me and three others were free!
I'm also planning on using it later this yeast ag the Pacific Science Center when I go to Seattle.
