We went here after doing the anhinga trail in the real Everglades national park. There we saw alligators and birds in their natural environment.
I can't recommend the gator park due to three reasons:
1)The airboats are overloaded 20people and the ride is very short (15-20min)
2)You don't see any wildlife because there are so many airboats that the noise distracts all of them. Even worse is the fact, that our airboat driver fed alligators and birds, so that they come out and tourist can see them!!!
3) there is an alligator show after the boat ride. But you don't learn anything about them and you can see that the captured alligator there really suffers. He looked as he were numb and didn't reacted at all. Maybe because he was under temperatures because there was no sunlight in his cage.
So all in all don't go there if you want to waste your money. Only go there if you have only 1h time for your visit and want to see an alligator and ride an airboat.
