You would have to call the resort for current monthly rates, when we were there we paid $750 (month). But that was more than 3 years ago. Yes, you would definitely have to worry about flood/tidal conditions, you are AT sea level, if conditions would warrant an evacuation, you would get yourself out of there. However, that area has not flooded in quite some time. The advantage of this area is that the storm threat is less than farther east on the coast....
