The only snake I've ever seen on property was on the walkway from BC to Epcot--much closer to Epcot than to BC. I saw an alligator and armadillo at CBR although I heard the story of a young boy getting bitten by a snake there. It is FL after all, and I'm sure being near bodies of water encourages their presence. However, "lots of snakes" is probably a bit exaggerated, in terms of proximity to guest rooms at least.
