Up to $100 onboard credit per cabin and two category upgrades lead Carnival Cruise Lines ‘Real Deal’ campaign for the peak wave booking period.

The offers apply to bookings from today (Boxing Day) until January 31 and cover cruises until August 31.

The deals are available on three to eight-day cruises, with itineraries including the western Caribbean, Nassau, Bahamas, eastern Caribbean, and exotic Caribbean.

Credit of $40 per cabin applies to three to four-day sailings, rising to $100 for seven to eight day cruises.

The initiative follows the line kicking off the year with its Beat the January Blues campaign which was followed by This Could Be You, and later, Think Caribbean, Think Carnival.

UK and Ireland marketing director Erin Johnson said: “We pride ourselves on offering our customers something different from other cruise lines.

“With the Real Deal, holidaymakers can enjoy extras on their sailings, allowing them to have even more fun whilst onboard our ships.

“The additional onboard credit can be used on our exciting excursions to suit the whole family, fantastic range of dining experiences, and alcoholic beverages.”
