This is as of 1/25/2011
Guests are NOT allowed to bring their own liquor onboard our ships. Liquor that is brought onboard at embarkation or during the cruise will be held until the last night of the cruise.
Wine Policy Guests are only allowed to bring bottle(s) of wine onboard NCL vessels for a corkage fee. When wine is brought onboard and served or consumed in any restaurant, public room/area, or in their stateroom corkage fees will apply according to bottle sizes noted below. This fee will be charged to the guest’s onboard account. Box wines are not allowed onboard.
Bottle is 750ml corkage = $15.00 USD
Liter Bottle is 1,000ml corkage = $20.00 USD
Magnum is 1,500ml corkage = $30.00 USD
Wines not purchased onboard are subject to a corkage fee including wines sent directly to the ship by travel agents, friends, family, etc. from another retail source.
NOTE: The policy regarding Liquor has not changed. Liquor (UK – Spirits) that are brought on board at Embarkation or during the cruise will be held until the last night of the cruise. The Freestyle Daily will list the location and time for pick up.
Since the policy didn't mention a limit on amount of bottles I asked and was given this reply:
There is no limit on the bottles; you just have to pay a corkage/handling fee for all bottles used on board.
For those folks who will undoubtedly try to smuggle alcohol on board in other containers, I didn't ask about the policy for other beverages (ie. water bottles, canned soda or juice) but the FAQ section on NCL.com states pretty clearly that you are not allowed to bring on beverages of any kind-alcohol or not. I'm sure people have brought beverages on NCL ships with no problems due to lax security, a loosely enforced policy, or personnel oversight but I wanted to share with you the information that I was able to track down.
Enjoy your trips to wherever you are going!
