Many people, when they are going traveling, try to save money on their luggage. If you're going on a cruise with a lot of dressier evening activities, you may want to consider a garment bag on wheels.
One idea that is quite common is to buy some very bright or easily identifiable ribbon and have that tied on to your Samsonite luggage. Sure, you can stop by a local department store and buy a thirty dollar suitcase, but it is not going to last. Cheap suitcases don't protect the contents as well as an expensive one will.
Some other sets find usage for business travelers. Consider obtaining a modest amount of foreign currency before leaving home. Items like blow dryers are not necessary, considering most hotels come with one.
Finally, luggage sets should have sections that can be expanded out if necessary. There are also jewel rolls or jewel rounds available if you're bringing along a lot of jewelry.
