There are floaties for use in the pools and ocean but they get snatched up quickly by the early risers. Many guests use these as cushions so they can be hard to obtain.  I would recommend that the first thing you do in the morning is go to the beach and lay out your towels on a chair or two.  If you want to grab a floatie do it then and put it by your chair.  Hopefully its still there when you return.  I always tried to find another guest who was in  need once I finished floating.  I really didn't care for them being used as chair cushions.  Floaties are a bit of a controversial topic among Sandals Resort guests.  Some advocate reserving a floatie and not giving it up.  Some believe they are for floating only and should never be reserved or used as chair cushions.  You'll find some lively discussions on floaties on various travel message boards.
