Necessities One of the most important things to remember is any medication you may require. Also remember comfortable shoes to get around on the ship and for walking at your ports of call. Sunscreen and sunglasses are a must. A good book is also great for some quiet relaxation. A travel iron can also be quite handy, as well as a travel alarm clock.
Hair dryers are able to be used on most ships.
All cruise lines require you have proof of U.S. citizenship. A passport OR a birth certificate along with a photo ID, such as a driver's license, is sufficient. Photocopies of birth certificates are not acceptable. They must either be an original, or a certified copy. Non-U.S. citizens require special documents.
