age limit for drinking alcoholic beverages in international waters on a cruise ship
As the legal drinking age in the United States is 21, no cruise line permits passengers under 21 to drink while in U.S. territorial waters. In international waters, however, as well as those claimed by countries with lower drinking ages, some cruise lines allow passengers 18 and over to drink. Azamara (azamaraclubcruises.com), Celebrity (celebritycruises.com) and Norwegian (ncl.com) allow guests 18 through 20 to drink with parental permission.
