Our local tour guide had a membership for this location so we decided to try it out.
It was somewhat for kids, but I did learn something from the exhibits, at least. Some of them were just videos, while they had some interactive exhibits. Mostly for younger audiences, though. The interactive exhibits were mostly occupied and difficult to get a turn on, mostly because little kids used them continuously.
The parking lot was hourly but they validated parking inside. At the time they had a sale on annual memberships.
With limited time to browse everything we just ran through every exhibit but we managed to see almost everything in all four floors. The only part I could not find was a way to get from the third to the fourth floor without using the elevator, which was too crowded.
There were some solicitors outside hawking petitions.
