The entrance to this aquarium is stunning and heightens anticipation for what you're about to see. We arrived at the Reef around 5:30p so crowds were not an issue. The lights, however, on the first few displays were turned off by this time (I'm sure out of consideration for the animals, but a disappointment to these humans). A great deal of thought went in to making the different exhibits easily viewable. This is not a full-size aquarium. Walking at medium pace, the entire shark reef could be seen in 30 minutes. Taking your time and watching some of the magnificent wildlife could extend your stay to one hour.
