Folks, Single use plastic, like straws & grocery bags are indeed a major problem. Aren"t your sign & sail cards made from plastic, & single use at that. The ducks are no differnt than the sand pails kids take to the beach, toys that are played with multiple times & are collected by staff & passengers alike. I hate to think how many single use plastic glasses are used on a ship in a week.
Some of the hidden ducks are keychains, card holders on a lanyard, magnets, earrings and I am cross stitching a fingertip towel with ducks & cruise info for my next cruise.
