Went on a Monday, 100°, but it was worth it. I had a free pass to get in. Admission for adults is $20.
Not sure what it's like to visit this place on the weekend but during the week on a hot day... There was probably ony 30 other people there. I was able to get great photos with most the animals. The dolpin habitat has upclose views of the dolphine pools from Above ground as well as a pool having an underground veiwing tunnel. Trainers perform with the dolphins every 30 mins. They switch pools and dolphins, each training session is different. The trainers offer open mic question sessions after each traning which i think is cool.
Behind the dolphin habitat is a white lion and tiger exhibit. There were a few leopards as well. The cats were all waking up from a nap when we arrived. So cool watching them play with large size toys. A few lions also played in the water pools.
I would recommend visiting this spot. It's something different to do on the strip. If you like wildlife, nature and want to get away from the desert for an hour or two the dolphin habitat is a spot worth visiting!!!
