There are a few reptile-related tourist attractions, all of which are super-fun.
Gatorland in Orlando and St. Augustine Alligator Farm in St. Augustine are cool. Gatorland raises alligators commercially, and has tons of them. SAAF has the only collection of ALL the alligator and crocodile species in the world. They are a zoo, not a commercial farm- their alligators are not harvested. Both have boardwalks through wading bird rookeries, in the swamp, with alligators. The birds are RIGHT THERE. It's soooooooo cool when they are nesting. Both have a few other herps, too.
Reptile World Serpentarium in St. Cloud is cool. The guy that owns it, George, is nice. It is a working venom collection facility, with a large collection of venomous snakes.
Deland has a small but cool venom-collecting facility, too, with some outside herp exhibits.
There's a Croc Encounter something or other near Tampa, I think. I haven't been, but it sounds cool.
I feel like I'm missing one...
Oh- Homosassa Wildlife Park is up the coast in Homosassa. They have birds, Florida native animals, rescue manatees, and if you go in the winter, the wild manatees are allowed into the spring, and there are LOTS of them.
Swimming with the manatees is fun. That's mostly a winter activity.
If you are going to sell reptiles, even one, you need the $50 annual Class III permit. FWC actively looks for people without the permit and without documentation of where they acquired the animals they are selling.
