Under Norwegian Cruise Line’s (NCL) popular "Free at Sea" promotion, there is no official "total daily limit" on the number of drinks you can consume, but there are strict rules per transaction. Eligible guests are entitled to two alcoholic beverages per person, per transaction, and each drink must have a menu value of $15 or less. If you order a drink that costs more than $15, you simply pay the difference plus a 20% gratuity on that extra amount. While the "Unlimited Open Bar" is technically unlimited, ship staff are legally required to serve alcohol responsibly and can refuse service to any guest who appears intoxicated. Additionally, the package excludes certain items like energy drinks, bottled water, freshly squeezed juices, and the mini-bar. In 2026, NCL also offers a "Free at Sea Plus" upgrade that includes these premium items and higher-end spirits. It is important to note that all guests in the same stateroom who are of legal drinking age must be on the same beverage package to prevent "sharing" of the benefit.
