We were just there Wednesday, we had a great time. The animals are really phenomenal IMHO, your son would be too small for the big coasters, but there's plenty to do and see to keep you very happy for a day or two. Between the skyway, the Rhino Ralley and the train, you do see an awful lot of animals, and then there are the walkthrough's where you can walk the path and just watch the animals in their habitat. It's really great. I'd highly recommend it.
