My wife just got a catalog from these people, and noticed they sell floaties very similar to the ones at Couples resorts. I looked on their web site and found them in many bright colors (sorry, no white or Couples logo).
Floaties like the ones they have @ Couples resorts are available in just about every swimming pool supply type store. It is also available on line and in pool catoogs.
Couples does not sell the Couples resorts floaties anywhere
They range in price depending on size and quality from $40. to $150.
