1-1.5 hours
Depends on how many exhibits you want to go through. Visiting all the exhibits will take you a couple of hours.
3 -4 hours
You can rush through in under 90 minutes, but if you really read, observe, and enjoy, 4-6 hours.
1-2 hours
I could spend 6 hours
About 2 hours. I had 3 kids, they could have stayed longer on certain areas. We skipped horror & breezed through Pearl Jam.
We spent a little over two hours, but took our time, and didn't rush it.
Honestly it took me about an hour as I skimmed through most and really read through 3 exhibits. But like many have said, it depends on what you are really interested in
1 or 2 hours
