First time cruiser heard lots of horror stories pre paid tips staff doesn't care about people since its automatic and people don't usually change the auto tip just pay extra in cash for good service but keep it even with poor service.
If I were to choose to raise or lower the auto tip for good or bad service not that I plan too, mid thru the cruise. what information is required to do so? do I have to bring my wallet with credit card or just picture ID and tell them what cabin I'm in?
Also can someone change auto tip for someone else in the same cabin ie friends/family going together under one credit card or do we both have to go?
