Until they close.
You'll not want to be in there much more than an hour or so. While it is cool, it's not so huge of a place where you could spend a hours.
There is no time limit how ever it is like one long line walking through. To send the maximum amount of time go when it opens. Fewer people more time to enjoy.
A day pass
All day pass
They give you an all day pass band so you can spend as much time as you want there although if you plan on swimming with the Aquatic Life it is limited to only the weekends on specific times
Until they close or you leave
There is no time limit, just until they are closed
As long as you want really.
No time limit
