I will be in St. Martin for a week at the end of March with six friends. Our travel agent has strongly recommended renting a car and has two on hold for us. Some in the group are worried about driving and safety, others are worried about lack of mobility. We will be staying somewhere by Cul de Sac. I personally don't want to be stuck in one place for a week. Suggestions? Also, what would the average cab fare be from the airport on the Dutch side over to to the Cul de Sac are? THANKS!!
