We are headed on our first cruise in February (5-night Caribbean). What is a good plan for packing and daily showering? Casual clothes during the day, back to the room for shower and nicer dinner attire in the late afternoon? My daughters are 8 and 11 and I figured shorts and tees during the day, change into sundresses for dinner? I'd probably be business casual for MDR (capris and blouse, etc.). Is husband ok in khaki shorts and polo? (My father-in-law will be a challenge. He's taken to dining in sweat pants since my mother-in-law, who was a tad controlling, passed away...)
