I am not a native Floridian, but even traveling to FL from NY for many years we knew Florida has Gators. If there is water, there is a gator-rule of thumb. Disney's water is no different than anywhere else in the state - remember WE are the predators, not them. BTW, since there may not be signs, please be aware that snakes live everywhere, not only in water-so please do not walk on the paths or in the grass. Also, we have spiders like the brown recluse, which can cause significant health issues, up to loss of limbs/ death. Please do not come in contact with a spider. Oh, and we have mosquitoes, so maybe Zika warning signs should go up throughout WDW. Sarcastic yes, but you kind of get my point. You are responsible for knowing where you are - and common sense has to dictate. We can't have fences and signs that prevent anything, and Disney should not have to share that 'risk' with it's guests.
