There's not much around Anse Marsel except a lovely beach and some pretty scenery, so I don't believe you'll find any type of school in this particular part of French St. Martin. Is this where you'll be staying? But, I did find a nursery school in Grand Case called "Ghislaine Rogers" located at 4 Rue des Ecoles that might be your closest option. But, from Anse Marsel the ride to get to Grand Case is going to be a challenge with the shortest route through the mountains. Sorry, don't know anything about this school and it's been almost 30 years since my wife and I dealt with pre-schools here in the states.
