Our kids just came back from Punta Cana and the beach where they stayed was completely unusable due to the seaweed the entire week they were there. They investigated ahead of time and had talked to people who were there the week before they were and there was nothing. This is going to continue to be a problem throughout the Caribbean....it is what it is. When we were at Orient in May we had 2 days where a "section" of the beach was involved. At least we didn't lose the whole week.
