We have been to both! We like Barbados but love St. Martin, Barbados is definitely more expensive! St Martin seems friendlier, more to do! Driving is not as easy on Barbados! We did enjoy Barbados but we have been back to st. Martin 3 times, our 4th trip coming March 2017. The groceries and eating was extremely high! Everything in restaurants are ala carte, almost $30 just for a decent breakfast. Any other questions just ask!
