Lots of beach clubs lined up along the same side of the island at PB. From PB you can see Mr. Sanchos, and a bit further down is Nachi Cocom. I think Sanchos is only AI now, they have water toys and several pools - my daughters lover the "lively" atmosphere. Nachi is also only AI, less crowded (limited to 130 guests per day), no water toys, and is very quiet and relaxing. Your call.
