Although there will always be people who like to complain, this huge change has been met with major approval from the cruise line’s passengers.

This hobby has become very popular on Carnival, Royal Caribbean, MSC Cruises, and Disney Cruise Line ships. Most cruise lines don't officially embrace duck hiding and just look the other way, but Carnival tacitly accepted it in November by adopting a duck-hiding-related on-board character.

Who to tip and whether you should tip extra at all is something passengers seem to all have their own opinion on.
