If you get tickets online its 18 for adults and 11 for kids children under 2 are free
General admission: Regular $20, online $18... Then there are bundles for film, and special exhibition (journey to space at the moment) GA $20, GA+JtS $28, GA+JtS+Film $36...all $2off for buying online
I got tickets online for a Sat and it was 18 for adults and 11 for kids. Really not sure about Sun pricing, but I imagine it would be the same
