When we do Sandals in Jamaica they usually have “Island Routes” tours. They have everything from a shopping excursion, to going to falls, museums, distilleries etc. seems to be the safest way to get out and about without getting hassled too much and they pick you up and drop you off at the resort.

Edit: when out don’t pick up anything you don’t intend to buy, don’t take an item they hand to you as they’ll expect you to buy it once you have it in your hand.
