On a Carnival cruise in 2026, gratuities are automatically added to your onboard "Sail & Sign" account at a daily rate (approx. $16–$18 per person, depending on cabin category). While these charges are technically "discretionary," Carnival's policy is that they are mandatory unless there has been a documented service failure. If you wish to adjust or remove them, you must visit Guest Services in person before the final morning of your cruise. However, completely removing them is highly discouraged and often requires an "approved exception," as these funds are the primary source of compensation for your cabin stewards and dining staff. Most travelers find that the automatic system is the most efficient way to ensure the hard-working crew is fairly tipped, though you can always add an "additional" cash tip for exceptional personal service if you choose.
