Minors
A passenger under 21 years of age must be accompanied in the same or connecting stateroom by a passenger 21 years or older who expressly agrees to be responsible for the under 21 passenger throughout the cruise. This includes, but is not limited to, preventing the purchase or consumption of alcohol and preventing the violation of any ship rules. If the accompanying adult is not the minor's parent or legal guardian, a notarized parental/guardian consent letter that authorizes the minor's travel and further authorizes medical treatment in case of an emergency must be delivered to an NCL representative at the pier.

An authorization letter is only required for guests under the age of 18.
Failure to produce this letter at embarkation may result in boarding being denied with no refund provided. Note: Two people under the age of 21 may travel together in the same stateroom without someone over the age of 21 in the same stateroom, if they purchased the cruise under the family plan and have at least one person who is 21 years or older in the adjoining stateroom.
