Flaka,
In case you did not get the point of the previous reply, you posted your question under cruise cuisine. Nothing to do with food, recipes, etc. Try it under a more general heading and /or the specific cruise line.
I would try to answer, but don't really know. I will say that 2 suitcases and a carry on per person is more than adequate if you pack well. I rarely even use the second suitcase.
Good luck,
Marty
