They last until they let about 100 kids run wild through the ship. Then you make a bee line for the nearest exit.
Depends on how much time you want to spend.
The guided tours are around a couple of hours. However, if you are interested in the details of the ship, you can spend hours. My wife and I spent 6 hours there and would have spent more if we hadn't had another time constraint.
I was there 3 hours but we walked thru you can take tours with a guide
We were there to visit for about an hour and that was too short
Tours are usually an hour and a half 2 hours
Their tours are about 2 to 3 hrs long
Sorry cant answer that but very interesting to ser
