If traveling to anywhere outside of the United States, you will need a passport. The only type of cruise that does not require a valid passport is one that begins and end at the same port in the United States. For these cruises, you will need to pack a copy of your birth certificate or proof of citizenship.
Your drivers license is an important thing to pack because you need it to verify all of your cruise and airfare tickets. When you reach your destination, you may choose to rent a car, which would require your drivers license and automobile insurance card as well.
Guidebooks and maps are not necessary items to have, but they can be very helpful on your trip. Make sure to pick up guidebooks and maps for all of the places you will be stopping on your trip. This will help you maximize the time you have at certain points of interest because you typically only get a day to explore each stop. Having a guidebook will help allow you to visit all of the popular sights and attractions in each place. Having a map convenient will make finding your way around much easier.
One thing many travelers do not consider when visiting foreign countries is that many other countries to do use the same type of power outlets that the United States does. Your electronics, such as cell phones, PDAs, cameras and laptops will most likely need to be charged during your trip. Research what type of adaptor will be needed for your destination as well as what types are on the cruise ship before departing.
In case of an emergency, you always want to have your medical insurance cards and medical history with you on trips. Having a copy of your medical history is especially important if you are traveling alone, just in case you get sick or injured and cannot answer for yourself or do not have someone else to answer for you. Having a list of your prescriptions is a good idea in case you get injured; doctors can avoid harmful drug interactions.
A foreign language dictionary is a good idea if you are traveling to a non-English speaking country. For example, if you are traveling to Italy, you will encounter people who do not speak English. To get around and find things and places you may need, a dictionary of the local language can be a valuable aid.
