Yes! Cruises go on sale often.

In addition to price discounts, a number of incentives are offered including onboard credits, free beverage packages, prepaid gratuities, and free internet packages. 

The best way to learn when cruises go on sale is to sign up for cruise line email newsletters & promotional offers, or promotional emails offered by your travel agent or favorite travel websites.

Also, on your next cruise, don’t forget to check on the sales that are offered if you book another cruise while you’re on your cruise. Often they will have great incentives for you to book your next one while you’re already enjoying a cruise! 

If you are or have been a member of the military in the USA or Canada, also check into military discounts for cruises.
