A decent aquarium, but small and disappointing. But, I wouldn't expect anything too terribly big from a Vegas hotel and casino. Near the hotel/casino, you'll see ads for the aquarium advertising sharks, but there's a lot more than that. \n\nThey are also accredited by the Association of Zoos and Aquariums, so it gets points for that. They also make at attempt at educating about conservation, so more points for that. They've got a nice selection of species for the size though. It's also a pretty good way to beat the heat, even though it's a bit expensive.\n\nOne gripe I had with this place was the line to get into the line to enter. Seriously? They also have one of those green screen photo ops set up, which slows the whole line down. I don't know about you guys, but I'd rather get my photo taken next to the real thing than have it edited in later. \n\nIn general, this is a good place to beat the heat, but there are much better aquariums out there.
