Went with my wife and daughter - almost $75 for the three of us, and that was just for the exhibit and general admission. Didn't include the planetarium, sky bike, or other extras.
The DaVinci exhibit was ok, but not near what I had expected let alone hoped for.
The remainder of the museum has a few areas appealing to adults, but mostly it's designed for 10-year olds. Yet, a lot of the hands-on stuff could be interesting to adults as well if it weren't for the horrible state of disrepair of many exhibits ... Broken lights, switches, parts, or it just won't work.
Three plus stars for a family with kids, minus at lead one for the cost and many broken exhibits.
