I've been here about 4 times since I've moved to Vegas. I always love to bring all my friends and family if they haven't been here yet. It's also great because they have a Vegas locals discount. :) Just a few bucks but hey anything helps!
I love to watch the dolphins! They are my favorite part of the whole exhibit. Even though there isn't a live show the trainers do work with the dolphins quite often so you are able to see them in action. I know they have an option to swim with them and if given the opportunity I would love to do that one day!
The lions and tigers were also great to see as well. It's crazy how huge they are. The day we went it was hot out so they were being lazy and sleeping but one of the white tigers was walking around so we watched him for a little while.
If you are a local or visiting Vegas this is one of the attractions I would say you have to visit-especially if you are visiting with small children-they will love it!
