Busch Gardens in Tampa is likely my favorite theme park I've been to. Besides 8 or so completely ridiculous roller coasters, they have a *serious* zoo. On their version of the Serengeti, the have herds of animals - a dozen of so giraffes, 6-8 rhinos, 20+ zebras, ibexes, etc. They have adult cheetahs in an area they can actually run around, tons of alligators, chimps, tigers, hyenas, 6-8 elephants. It's crazy and definitely worth stopping through if you're in West Florida.
I guess that video is a bit old because when I was there, the big tank with the Malawi fish had a hippo in it and the smaller one to the right contained the crocs.
While there were a ton of fish in there, there weren't as many of the large specimens as in the video. Still an amazing site though.
