I certainly don't want to toss a crimp into your plans, but because your kids love what they do,and the need for gluten free, I think you could have a difficult time finding a place where you will all be happy.
But, in St Maarten....We dined on the French side, in a cafe by the harbor. There were lots of little places right there, in a fabulous setting. If you try a google search, send off some emails to the places,and ask about your options, and see the menus.. There will be offerings that will tempt the kids and yourself...I think possibly the gluten free, will be tough..hopefully not...
