We spent a good two hours there and only got through 2 or 3 exhibits taking our time and reading. I feel like we probably could have spent a couple more there no problem.
3-4 hours
You could easily spend all day here.
It took me about 3.5 hours
4 to 5 hrs.
I'd say the people are right in saying about 3-4 hours if you want to see everything
Minimum 2.5-3 hours, maximum- no limit.
A few hours, I'd say. I go frequently, but could spend the whole day myself. It depends who you go with. I like to see all the movies/planetarium stuff! That takes up some time.
It depends if you like to read everything! You can definitely walk through in half a day. But if you really want the content it takes longer, like any museum i suppose.
As adults I'd have to agree that 3-4 hours would suffice.
Probably 2-3 hours, maybe a bit longer if you have never been, plan on catching a movie or a bite to eat. I go about once a month, and am typically done in less than 2 but don't take in all the details each trip.
If you have kids with you that want to check it all out, maybe 3 hours
