I also have a suggestion - cross pack. Hubby and I lay everything out by category in the guest bedroom and then we divide each stack by the number of suitcases we are taking so that a little of everything goes in each suitcase. That way if a suitcase doesn't make it, at least we have changes of clothes. After all, why would you want to spend your time in Europe shopping for clothes to wear on your cruise.
If some of your luggage gets left behind, it might take a while to catch up with you.
