It's something to do to get out of the heat but is definitely overpriced. I did use the after 4pm discount that offers $25 admission from 4pm-8pm. You will easily walk through all exhibits within an 1 1/2 and that includes seeing the 3D movie and the carousel aquarium. The employee's script delivery during the carousel show was labored and hard to sit through -- they definitely need more practice. Crowd flow management in the exhibits is also another problematic area. They are fairly new so hopefully through training and daily experience the flow will get better.
