We had fun, and there's a lot to do and see. However most of the exhibits have some broken parts, and several exhibits were completely broken. Additionally we went at around 1100- and the place was overrun by "Lifetime Fitness Summer Camp" and crap like that. I completely get that it's not reasonable to expect a 22 year old gym rat to actually supervise 25 6-9 year olds, but that makes for a rotten trip for everyone else. My 3 year old was actually PUSHED by another kid who kept following us exhibit to exhibit and trying to shove my boy out of the way. At this point I want to grab the brat and shove him out of the way but that's how the cops get called. In short, we had fun, it's a little broken down, and if you go, make sure you arrive after 2 PM. Other individual parents were all pretty good about not letting their kids be a**holes but the unruly kids from daycares had a field day bullying littler ones. If I had paid full price as opposed to the Groupon I found, I'd be pretty displeased.
