What will the drinking age be for the Ultimate World Cruise and the four Ultimate Cruise segments?

Twenty-one is the minimum drinking age onboard sailings departing from the United States, Canada or the United Arab Emirates. On sailings departing from the Caribbean, South America, Europe, Asia, Australia and New Zealand, it is 18 unless the home port’s legal drinking age is higher than 18, in which case the higher age applies. This applies to possession of alcohol as well.
