Because we usually add on an additional land portion to most cruises, luggage and formal clothes that are not needed become a hassel. Plus we could use that tux space for our shopping purchases. I'm for elgantly casual. Even coats and ties for some nights. I guess it time to get hubby a good black suit to sub for tux and a nice formal tie following Ken's example. With all the traveling they do, they have it down to a science.
