we did it in 2hrs,but we couldn't really read everything,so i suggest going early and staying for about 4-5hrs if you want to enjoy your visit and learn about our history fully,its a big museum and you gonna need alot of time
I would recommend mutiole visits...It took me multiple days...There is so much to see and you would not want to rush!
I suggest more than one visit to fully enjoy the experience
I would suggest the entire opening hours if going during a popular time. There are 3 floors up, and 3 floors below ground.
It is very large and unique musieum, consume one full day.
