We were in Playa del Carmen in April. The sargassum was awful. We had about 2 of 7 days we could get in the water. Solid masses of it stretched out about 25 feet from the shore. Hotel worked like mad to bury it, but it made little difference. The next day....all back again. This was our first trip to Mexico, and while certainly nobody is to blame (well, maybe Mother Nature) we reaffirmed why we go to Negril. I wouldn't have cancelled my vacation over it. We're pretty easy going, but we were all bummed to not have much water time while we were there.
