For JVD this week we went with Nadine at Paradise for 7 seater car for week was 600 so I assume $80-90 for a day.
https://paradisejeeprental.com/Located past Christine's bakery to right. Recommend you eat at Hendos, Tipsy Shark or harris with Cynthia. The cruise ship that made its stop here cancelled the visits... in any regard they stay at the far west end of White Bay in their designated spot for the most part. I don't know when you are coming down but you can check cruise schedule at top of this page
