Make sure you buy the ticket online before going. Although we waited 30 minutes to get in, it's not overcrowded inside. It's pitch black inside with projectors on every wall and floor. It would be difficult to take pictures with a cellphone, so bring your DSLR. Set your DSLR to manual, 800+ ISO, F2, 1/30 would work for most. The musuem is like a maze, there are two separate stairs going to 2nd floor. Go up if you happen to see the stairs or you will be walking around later and won't be able to find a way up. You can easily spend 3 hours in there as each exhibit has multiple variations.
