Coming to KW in November and we will rent a car in Ft. Laud. at the airport. Driving to Key Largo for a couple nights, then on to KW for 5 nights. I will be using c.c. points for the rental.
Any preference in rental agencies? I've read about transponders?? What are they, do we need one? Insurance?? Just want to be prepared when we get there, don't want any "costly" surprises!
