My wife, 8-year-old son, and I all had a great time at this place. Along with enjoying all the fascinating animals, we also learned a lot.
There were all variety of reptiles, from tiny little frogs to huge Nile crocodiles (awesome!). Turtles, lizards, snakes, etc.
We lucked into seeing an alligator-feeding, that was real cool!
There are constant little presentations ("shows") throughout the day, you can check those out or ignore them. We went to two and enjoyed them both, the keepers were very knowledgeable and friendly and answered everyone's questions, even the silly ones from the little kids.
Cost $45 for the three of us, but seeing as we were there for over 3 hours, that was a good value.
