We were planning for a cruise. There is a limited amount of storage space in the crowded cabins, but when packing for 15 nights, you need a lot of clothing. My wife and I both got two of the Jeep brand hardside cases, the 28" and the 24". They met the requirements for check baggage on both the airline and Amtrak. The smaller case fits inside the larger one for storage, both at home and on the cruise. They can be nested open also, to allow them to fit under a bed for storage. The cases are rugged but very light, about 8+ pounds, but have wheels and a pull handle. The case is closed with a zipper, and that might prove to be a weak point, but no trouble so far. Plus they come in two colors, my wife got the read (which looks orange) and I got the charcoal. Our Jeep brand pilot cases actually fit inside the 24" hard side case so you can nest three bags in the space of one for storage. Online price comparisons put Walmart.com at the top of our list by a substantial margin. The price paid was excellent, and could not be found lower, in my opinion.
