COmplete waste of time. It took all of 10 minutes to look round. Mainly just photos of things. Doors to anything interesting were locked shut, anything interactive was not working and there were no staff around. The only thing of interest was the challenger simulation, but it was an extra $30 each! Simply not worth it! It took longer to process my refund than it took to look around this place. Go to the phoenix science museum, you will have a great day out there!
