Carnival Cruise Line is increasing gratuities and some other onboard charges from next month.

The suggested gratuity payment will increase by 51 cents a day, the first time the cruise line has raised its gratuities guideline since December 1 2017, according to the website Cruise Hive.

Cruise Hive reports Chief Operating Officer Neil Palomba told clients in a letter: “Effective with all cruises departing on or after 1 May 2022, we are making adjustments to our recommended onboard gratuity guidelines.”

Wifi, beverages packages and speciality dining prices are also going up, with an additional 18% service charge for beverage purchases added from 1 May and increased cover charges for Chef’s Table, Bonsai Teppanyaki and Bonsai Sushi.

Guests travelling after 1 May can pre-pay gratuities and the other charges at current rates through their My Cruise Manager profile management system.

In a message to travel agents, the cruise line said: “Although we’ve done our best to minimise the impact of rising costs, we will be implementing nominal changes to some of our onboard services while still providing your clients the best vacation value, on land or at sea.

“Please encourage your clients to reserve pre-cruise (on My Cruise Manager) before May 1 to save on these categories.”
