In 2026, you cannot purchase a "single day" drink package for a Carnival cruise. Carnival’s beverage programs, such as the CHEERS! all-inclusive alcoholic package and the Bottomless Bubbles soda package, are designed to be purchased for the entire duration of your sailing. If you decide to buy the package once already onboard, you must typically do so on the day of embarkation or by the second day of the cruise, and you will still be charged for all remaining days. This policy is strictly enforced to prevent guests from "sharing" packages or concentrating their drinking into a single 24-hour window. For short-duration sailings or for those who only want to drink occasionally, the best alternative is to pay "a la carte" for each beverage. Notably, for sailings departing from ports with specific local taxes (like Texas or New York), the package usually becomes active at 6:00 AM on the second day of the voyage, though you are still billed for the total length of the cruise.
