. . . I have to tell you though, there's no way in the world that I'm going to be able to pack for the cruise in his "big packpack."
I travel to Europe often with a Rick Steves "big backpack" carryon. One time we spent two weeks in France and Spain with just one piece of carry-on luggage each. It's very convenient to travel light, especially when taking public transportation (many Metro stations have stairs only).
