None at Maho, none at Cupecoy, none at Happy Bay, none at Orient Beach. And we were at Orient three days during the week. We were pleasantly surprised !!! And plenty of beach in front of Maho, and even just to the left toward the airport road there was still a little beach. Then, of course, rocks the rest of the way toward Sunset Bar. But at least we didn't encounter any seaweed at the beaches we frequented.
