Secrets

Hi. I’ve done several cruises but recently heard that stewards and cleaning crew on some cruise lines treat guests differently if they do an additional tip up front at the beginning of the cruise than they would if the guests didn’t tip up front. Is that true?

Also, I heard sometimes there are secret markings on or around the cabin doors that are used as indicators about their experience with those guests. Is that true?

If you’ve experienced this, which cruise lines and how long ago?
