I took my family there this weekend. With parking, the total cost was $120. Totally not worth the price. We generally take our kids to science centers when we visit large cities. The unanimous assessment by our kids was that this was the worst one that they have been too -- yikes! The displays were not very good for kids (maybe 1 out of 20 were appropriate for kids aged 8-15). For kids less than 5 - the children's looked good, but I think you had to be older than 17 or 18 to follow most of the other displays. Also, many of the displays either did not work, or only partially worked. I thought that the construction of the building was very nice (although there was a lot of unused space), but they obviously put less effort into creating a truly compelling and inspiring learning experience.
I think they need to really look at their pricing -- If it was 1/3 the price (and they did not charge extra for parking) - I would have felt a little better about the experience.
