Can I purchase a beverage package for selected days?
No. Holland America Line beverage packages must be purchased for the full length of the cruise, and they must be purchased by all eligible stateroom guests who are of legal drinking age for the itinerary.
What this means
You cannot apply a beverage package only to specific days of your voyage; the package applies across the entire cruise length.
If a beverage package is purchased, the purchase requirement applies to all eligible guests of legal drinking age in the same stateroom.
