i personally have been cruising since the 1980's and have never taken most of the stuff on this list. I cruise at least twice a year or more. You are really overthinking the packing. The one time I actually needed duct tape (broken zipper on a suitcase) a simple call to housekeeping brought a man to the door who not only supplied me with duct tape, but help me wrap my suitcase to get it home. Pack lightly and don't schlep all that stuff around. IMHO.. enjoy your cruise.
