If you are a history buff, you could easily spend a couple hours, reading everything, pouring over maps, listening to audio components, etc. But for the casual fan, probably 30 minutes is nice.
I only had an hour at the museum and barely did as much as i woukd of liked in the Worlds Fair, Had to rush thru the Panorama's section
It can be an Enjoyable 3 to 4 hours taking your time just relaxing reading and seeing the many history exhibits. 👍
It can take a couple hours to less than a hour. It depends how In depth you like to read the information next to objects / in the exhibit. If you just plan on looking without reading anything you will go through quickly.
I have no clue
20-60 minutes depending on how much you want to see exactly.
