Be ready to produce at the airport or customs your passport or identification and your cruise ticket too if required. Never forget where you have kept those to remain free from tension and any awkward situation. It would be fine if you keep all those in a small case like a business card holder. Keep it in a safe but quickly reachable place.
To keep copies of your passport, visa, driving license, and other important documents would be wise. That applies for your traveler’s checks and credit cards too. For maximum safety precaution, keep at your home a set of the copies with a trustworthy person who is capable of taking out quickly those if your need be, while in the ship’s safe or in your cabin’s safe, if there is one, keep another set. Retain with you the originals and a set of the copies, in different places though.
