I always enjoy seeing live animals, and this place has them! I gave it 3 stars because it's kind of touristy...but thats basically what Vegas is all about.
I enjoyed seeing the white tiger and the white Lion (I've never seen one before, and it was pretty cool). All the big cats were beautiful, but some of them were rather shy :/ None of the animals were very active...even the dolphins seemed somewhat subdued. There were also some alpacas that were kind of funny...but nothing to write home about.
If big cats and dolphins are your thing and you have some extra money that you don't mind spending, then hit this place up...I would personally choose Shark Reef over this place...but it wasn't too bad.
