The amount of savings attainable with a Carnival Cruises promo code depends on the promo code and the cruise package purchased; for example, a promo code for 30 percent off a $1,000 cruise fare yields a savings of $300. Both RetailMeNot.com and CouponChief.com offer Carnival promo codes.
While some promo codes for Carnival offer a percentage off the cruise fare, others offer a specific dollar amount of savings off cruises of certain lengths. For instance, a code may offer a savings of a specific amount of money off a three- to eight-day cruise, with additional savings if three or more guests book the cruise through the code. Other promo codes offer on-board credits and last-minute cruise bookings.
