Cruising during the holidays can often mean more crowds and higher fares, says Colleen McDaniel, managing editor of Cruise Critic. By booking a cruise for January, February or March, you can take advantage of lower fares, avoid the holiday crowds and beat the spring break rush. The industry's “wave season” also takes place during that time, when cruise lines offer added discounts that may help you save even more on your trip, she says. You can score some of the best cruise deals if you book at the last minute -- just don't expect the really cheap tickets to get you a stateroom with a view.
