It is the responsibility of all Non-British passport holders to ensure that they are in possession of a valid passport, and any necessary entry visa or permits for their chosen cruise. If you are unsure of whether you are required to obtain such documents you MUST contact your travel organiser, or the relevant Embassy or Consulate for advice.
Failure to comply with this request may result in refusal of carriage, or the imposition of individual fines by the local immigration authorities.
