Wow! Thank you everyone for all the great advice! :-)

The home to the north comes with its' own 21 ft skiff, but we are limited to getting a ride to SP only once per day and I think we'd need to find our own way back home from SP once we get there. I've grown up with boats my whole long life, but don't know if we could convince the owners to allow us to take the skiff ourselves after a few trips with him?

If we stay in the far south, we would definately rent a golf cart.

The home in the south is on the AC satellite map from another thread but the home in the north is not, and is in the blurry map area.
