Cruise Ship question

[DuzyEverwork]

A very good friend of mine is going on a 21 day cruise on the Queen Mary 2 in October (lucky s*d!), she has wanted to do this for more years than I can remember and at last her dream has come true.
I would like to buy her a little something which she can take with her which will be useful on her trip. I have read a lot of the forums who suggest sun tan lotion, medication, lightweight jackets etc but they are just not what I want to buy, does anyone have any suggestions please?
