Tours are self-guided unless you have special arrangements with the museum.
Yes definitely 2 visits are needed
Most don't have enough time to see everything in one visit. I suggest you select a time limit, and then select exhibits on your list of must see items tailored just for you.
Approximately 4-5 hours if you see everything.
What time are the daily timed tickets available
Agree, at least 5 hours, better a second visit. Or from 10am until the closing at 5:30 pm.
There's a lot to see. A second visit would be good to really let all that info sink in. It takes about 5 hours to see.
We did not take the tour, but I recommend 2 to 3 hours with a break for food and drink.
