I was there in March. When you are on your chair, you don't have to wear a mask, but when walking around (other than to/from pool & beach) you do...that said, many people are taking this interpretation loosely and there is a general lack of compliance with wearing a mask among a good portion of the guests. All seemed to be good about wearing a mask inside the hotel though. And I never saw one staff member NOT wearing a mask. I think staff members are trying to enforce it, but are obviously overwhelmed.
