Yes hire a car. Yes drive day or night .
Get clear instruction as to where you are going as many roads over lap and return to same start... can be fun
Locals are great at giving directions may offer to hop in and take you down the street .. to where you are going as a direction guide .
Never had a local hop in at lights is that Jamica not Barbados . I hire car each year for past 12 years and drive day and night as female. NEVER a issue..
Never pay to have car watched what for will some one steal it that is for police and the car insurance you have just purchased.
Do not do silly things leave car unlocked withs goody in car, or leave key in car stuff you would NEVER do at home.
Be ware island police have speed radar and Breathalyzers for alchol..it drinking do not drive then take taxis.
