From the map they provide on VBBO, it looks like it is just left of the Hotel Beach Plaza, which would be between the bridge and the cemetery. I can't find a name for the building. To us, it looks like it would be a long walk to any beach bars etc., except for the town of Marigot, and I couldn't find any beach bars there. We think Dreams would be a long walk from there? Might have to keep looking.
