This is prime time for repositioning cruises, commonly called "repo" cruises in the industry. As lines reposition ships from summer locales such as Norway or Alaska to winter routes in the Caribbean or Mexico, the trip itself becomes a money-saver. The per-day costs and the ports-of-call are where you'll find value, not necessarily on the bottom-line costs. For a comprehensive list of repo cruises, visit About Cruises. Book early, as repeat customers tend to fill these cruises quickly.
