Gatorland's alot of fun. My 7 and 8 yr-olds really liked it when we went last December. It seemed well run and was clean, and the animals appeared well cared for. There was actually alot to see and other animals besides Gators (birds, lizards, and Giant tortoises , as well as a playground, a small train ride (costs a little extra) and various shows. I think it would depend on whether your 3 year old would be scared by Gators. They can be frightening to little kids when leaping up to grab their dinner (dead chickens) as they do in one show. Most things would probably be fine for a 3 year-old, though.
