TravelTalkOnline Forums Travel and Vacation Forums St. Maarten - St. Martin Public buses/van use from Grand Case

Use of public buses from/to grand case. We will be in grand case in November and are curious about these. We would like to travel to other beaches without the worry of driving our rental car. We were in grand case last April and never saw a bus stop. Just not sure how the system works. Times? Where do they go? And how do u know if/when they come back. Do they take u to the Dutch side also. Thanks in advance for help!
