Have a wonderful trip! I got a lot of good tips from cruise critic (where I see you have been already). One of the best tips was to take a shoe holder to hang on the back of the bathroom door to hold all your little things---it sure made things easier since there is limited room in your cabin. We kept just about everything you can think of (that will fit) in ours. You can buy a cheap on at the dollar store, or a nice cloth one that you can save and reuse.
I would also recommend taking some sort of motion sickness medicine, or ginger vitamins, just in case. I didn't used to be so sensitive to motion, but in my middle age, I seem to feel it more. Last time I took ginger vitamins 3 times a day and didn't get the drowsiness that I got with the Dramamine and Bonine.
Have a great trip!
