A year ago I stayed at Captain Morgans for a week. Rented our golf cart from a place that was walking distance from the Tropic Air terminal. We walked to our right (that's south I believe) out of the Tropic terminal and the cart rental place was not more than a block or two down (I can't recall the name). I suggest you bring cash and negotiate your rate. I would think you could get a cart for a week for under $250; perhaps less since Oct is their low season.
