We will be flying to Vieques probably on a Sunday for one day only, and I have a couple of questions. If we want to go to Blue Beach and Esperanza, should we get a rental car, or will taxi take us to these locations? I don't mind paying for a rental car if needed, but if taxi service would be reliable, would it be better option to visit these areas. The flight arrives about 7:30am and leaves the island around 6pm. Also, are the weekends busy on Vieques, and are the shops open on Sundays?
