It seems like most cruise lines have informed their crew of the cruising duck game, and the crew can even get in on the fun if they wish. As the trend was getting started, some crew members would throw the ducks away, but as the trend grew in popularity this no longer became an issue.  The game is most popular with Carnival Cruise Line - where the game originated - and the crew of this cruise line have totally embraced it! John Heald, a brand ambassador for Carnival, has stated that crews are aware of the cruising duck trend and will never throw a duck away.
