What to Pack for a Cruise: A Beginner's Guide There once was a not-so-savvy seafarer who didn't feel right unless she took two steamer trunks crammed with outfits on every cruise. This, she learned, was not a good idea. Besides incurring the wrath of her male traveling companion, who pointed out that he would have to wrestle with excess baggage through airport terminals and beyond, she quickly tired of cramming her belongings into tiny closets. The now savvy seafarer follows this packing rule: Thou shalt put into one's suitcase only that which will fit neatly in the allocated cabin storage space. Following that advice is getting easier because, for the most part, cruising has become a more casual vacation with relaxed dress codes. Plus, with airlines charging to check bags, it's just plain economical to pack light. To do so, you need to have a good sense of what you’re going to wear on a cruise so you don't pack your entire closet. If you're wondering what to bring on your next cruise, here are our guidelines for what you'll need to pack.
