I play at Cane Garden Country Club quite often since it's only ten minutes away. On the Hibiscus nine layout you'll be instructed that the 'out-of-bounds' that are marked with red stakes, not white, means you don't look for your ball beyond the red stake. Hibiscus is a very lush and tropical layout, but it's also very rugged and the red stakes can come right up to the edge of some fairways and if you stay out of those areas you should be alright.
I haven't seen any snakes in our ten months here, but at Cane Garden I've seen up to five gators at one time on the Alamanda nine in the area of the two lakes near the 6th green I believe. I never understood why people pay extra to live on the water here.
