I rather enjoyed my day here. Note that I visited alone on the Community Day for $1.
The venue, naturally, was crowded. The majority of visitors were families with children, so it got rather loud, and many of the activities were being used at a time so it was hard to get to all the attractions. However, this did not impede exploring, because in many cases watching someone else interact with an attraction was enough to understand it or be fascinated by it. There is a lot to do here - maybe even too much for me - and I think a $30 price tag is justifiable if you spend a good bit of time here and go through most of the attractions and perhaps even a short film screening.
