The next time we go to Europe (Nov. 2009) I plan to take only a carry-on bag. We'll be on Carrnival, so we can wash our clothes as often as necessary. Hauling luggage around Europe can be a major hassle. We've been on so many cruises now that we don't go to the dining room much anymore, so that cuts down a lot on clothes. We met a guy on our last cruise who travelled with only a backpack. So, it can be done!!!
