Cruise Beverage Packages 


Note: Royal Caribbean changed its drink package policy as of August 1, 2025, eliminating the previous option for exceptions to the Deluxe Beverage Package requirement for non-drinkers in a stateroom. Now, if one adult in a cabin purchases the Deluxe Beverage Package, all other adults of drinking age in that stateroom must also purchase it. This change was implemented to prevent guests from using the exception as a loophole to share packages and order drinks for more than one person with a single package. 

 

All prices are per-person, based on a double occupancy of the stateroom and are quoted in U.S. Dollars unless otherwise noted. Prices include cruise fare and mandatory taxes, fees and port expenses.
