It will be intriguing to see what becomes of the zoo as there are only 7 exhibits there. When I visited in 2017 there was a total of 10 dolphins (in two pools that were connected) and then 6 exhibits of big cats. There were a couple of tiger enclosures (orange and white tigers), an African Leopard (black), an Amur Leopard and a couple of enclosures for White Lions. That's the entire zoo and obviously the dolphins will be the most difficult to find a home for should the zoo ever close down.
Also, inside the lobby of the Mirage Hotel is a 53-foot long aquarium tank behind the check-in desk. It is 8 feet high, 6 feet wide; it has 4 inch thick acrylic and holds 21,000 gallons of water. For a random aquarium in a hotel it is really nice and it was teeming with all sorts of colourful fish and even a few eels back in 2017.
