I would choose Harbour Club because it is in SeaPines, which has wonderful bike trails, close to the beach..by bike or car, is in the heart of Harbour Town with shops, restaurants, marina, etc just a few feet away and most of all because we own there and just love it. It is also close to South Beach with all their shops, restaurants, etc and Coligny Circle with the same amenities...shops, restaurants, beach, etc. Even if it's not swimming weather, it is certainly beach weather..
