Another way to save $, book out as far as possible. We have been booked for our cruise since October 2004 (we aren't going until March 2006). Because we booked out so far we were able to afford going up a few decks and having a porthole. Our current cabin and cruise is now over $2,500 more then when we booked. Even the lowest category cabin is more than what we paid. If you can plan out, that can help you save costs.
