I was also there last Wednesday, and the times HydroGuy mentions are right on. My family agreed that it might be worth about a 20 minute wait once during a visit, but that is about the limit. We went to Nemo directly at the 8:00am park opening, and were walking off the ride at about 8:35am.
We were also in the park on parts of Nov. 18 & 19. The board by the hub usually had the wait time for the ride at 75 minutes, with it being lowered to 65 minutes late in the afternoon.
