A jitney??? What's that? There are busses, but they are not on any kind of a schedule. Take a cab. It will be something like $10, plus a fee per bag. If you want to mess with trying to catch a bus around later, after you have been on island a day or two, fine, but after a long day of travelling, take a cab. ...and frankly, once you get there, rent a car for at least a day or two. Very difficult to get around and to discover different parts of the island without a car.
