We are coming to Exumas for the first time in November. We like to explore deserted beaches which I am thinking may be off Queens hwy down dirt roads or unfinished tracks of land. (We visited Long Island last year and it was this way) Do you advise a jeep or 4wd as opposed to a regular car rental? We would like to visit every beach possible and will also rent a boat for the offshore cays. Thanks for any recommendations.
