As an adult who loves aquariums, I love to hit up this pavilion as close to opening as possible. That way I get my picture with Bruce without a million kiddos running around, and my husband and I can leisurely stroll through all of the exhibits and not feel rushed or crowded. But to piggyback on what someone else said, you shouldn't need more than 1-2 hours for this pavilion, considering there are only the two rides and then the aquarium exhibits.
