My Family debated over traditional luggage or duffles for a couple months, we decided on duffles and a nice garment bag (for fancy duds). So far we love it, especially for cruises. The duffles stack neatly when empty and we can usually fit 4 empty ones on the top shelf of the closet. They fit under the hotel beds nicely too. No tripping over bags in the middle of the night on the way to the bathroom.... Great for storing at home under our guest beds too, no more bulky storage. After researching we decided on LL Bean Large Rolling Duffles (we each picked out our own bright color) the only drawback is they do not stand upright on thier side. They are lined with a waterproof fabric and they sell a 3 pack of gear bags that fit perfectly in the bags. The large is a good size and its easy to handle/manuvure and keep to the airline weight limit with it. (My aunt has the extra large and has to pay overweight fee when she fills it up). We are able to fit about 10 days of "regular" clothing (for our alaska trip we used a seperate one for our bulky jackets and sweaters, for our Caribbean Cruise everything fit into one bag no problem. I guess it depends on what kind of a packer you are (me heavy, my DH Light)Alas you clothing does require some ironing upon removal, but a better packer might be able to avoid this. Rolling clothes and such...... They hold up well just a few scuffs from overzealous baggage handlers.....Happy Shopping....and Happy Travels......
