Interesting place and it's even better when you can check it out for free with the MyVegas points, otherwise it's $20.
They have a dolphin exhibit where you can watch them get fed (imagine if they did that with tourists at the buffet) and they also do a few tricks but it's not a "jump through a hoop show", instead they do a few flips and play around. The trainers know their stuff and invite questions and also stick around to answer questions after the feeding. I do wonder if they really have a big enough pool for so many dolphins but that's another story.
The other part of the the garden is an area where you see lions, tigers, and leopards. The animal exhibits aren't huge and I wasn't thrilled to see the leopard pacing alone in a small cage. Seigfried was there so we met him and that was pretty cool! He also mentioned the cats live in a larger area behind the exhibit and they are just chillin' in the areas we see for about four hours before they rotate them out for another cat. You can tell he knows his stuff and cares about them, he said white tigers are extinct in the wild since they don't exactly blend in well. Also, one woman was pacing with the tigers outside the cage and talking to them, only Vegas.
Interesting place and worth checking out if you're into animals. Remember it's more like a zoo than a show so don't be shocked in they're asleep when you walk through.
