For diabetic travelers: Have your medical doctors write a note stating you are a diabetic requiring needles and refrigeration for your insulin. This usually makes it easier to get the refrigerator emptied. If your cabin doesn't have a refrigerator, you can usually rent one for a minimal charge. The letter comes in handy with security when questioned about the needles. Also the ship will provide a needle disposable bag. The small chocolate candy that's on your pillow every night comes in handy if your sugar drops.
