It depends, you can stay more than 3 hours if you need to, I did it under 2 hour before I rode the ORLANDO EYE.
Lol we was in there a long time.. 2 hours. But I dont think the older lady that worked there like the fact was was lagging behing.. oh well..
Yea around that maybe longer depending on the crowd
Ok cool
When I went it was not so busy which was good
When I went a few weeks ago I was only there for maybe about 2 hours max, the museum isn't really that Big in my opinion.
