I think there's both a French and a Dutch Cul de Sac, but Mark's is definitely on the Dutch side, in the parking lot of the Grand Marche at the roundabout near Philipsburg. Not in the shopping area near the boardwalk, but I think it's still considered Philipsburg. Street addresses have never been of any use to me there, as there were no street signs until recently, lol.
