There are Seven (7) floors (not 9). Basement, and 1-6. Basement is for special exhibits and costs extra. First floor is mostly entrance, an aet exhibit (rotates) and a VR experience. Floor five is more rotational art and entrance to the theater for shows (cost extra). 6th floor is a restaurant. That leaves 2-4 for the main parts (mostly free + Tour of DC ($$)). 2 & 4 are easy 4 hours each to read everything, or 1.5hrs to get through. 3 is short videos in 2 theathers on the NT, a replica mini village, and a light show tour of the OT. Total floors 2-4 are 4-10 hours, depending on your interested. Took me 4 visits to see it all.
9 - 8 hour days to read everything.
About 5 days
There are nine floors, maybe 3 days, alot to take in
We were there 6 hours and didn't get to see everything.
Not sure about the entire museum, but we spent about an hour on the 3rd floor, and then they closed so did get to explore the rest.
