We are in Tortola for one day in a couple of weeks. Vacationing w elderly parents (3 of them - sort of a last hurrah). Ideally we would rent a car and explore all day but am concerned that its too much for the old folks and we 5 won't be comfy in a jeep. And I'm not sure plopping my MOL on a beach with a thousand cruisers will be appealing to her. Help??
