How many hours does it take to finish the museum?

Hours? Two days!

2 hours is enough

I would say 4¹/²hours give or take, if you quickly browse around an area or two. It all really just depends on you. However, I think it's enough to go around and see to fill your day.

I would say three but it depends on you and how much time you spend in each area.

Between four and five hours
