How much time does the tour take?
About 20 minutes for the glass-bottom boat.
You can spend as much time as you want observing in the underwater tower

If you do both the boat tour and the underwater observatory tower,
it will take you from one hour to an hour and a half, including the time it takes from and to the parking lot.
Is there an age limit on those using the facilities?
There is no age limit.
But you have to descend a steep spiral stairway (50 steps) to enter the underwater observatory tower,
and you have to walk across a floating pier to enter the glass-bottom boat,
so be certain to confirm in advance concerning people who have difficulty walking,
pregnant women, and people accompanying small children.
