Great experience. If your driving and parking at self parking, expect a long walk through their casino, restaurants, arenas, Starbucks and pool before you arrive at Shark Reef. We arrived here at 12:30 pm on Thursday and the lines for the ticket window wasn't long. We got the local discount since I have a Nevada state drivers license. There is an escalator which takes you up the entry way to aquarium. Before you can enter, you have to wait in line to take the group photo whether you plan on buying one or not.
Once you walk in, the walk way is made of concrete and they are angled downward so be careful if you have a wheel chair or small kids. The displays are great for all ages including a large shark tank, komodo dragon, and alligator.
