It's usually pretty rough, yes. Often people use boogie boards, etc., there. No amenities on that beach, although presumably most rental units at Guana Bay provide chairs/umbrellas/coolers for their tenants. And, as the op said, it is somewhat out of the way, for the main tourist areas of SXM. I personally didn't care for the weird, kind of futuristic look of the whole place, so not sure I would stay there again. But if I did, it would be to rent an individual unit, based on pictures and reviews of that individual unit. Guana Bay is a very residential, quiet area, which some people would like. For me, I didn't care for it.
