An expanded room service menu which carries fees for certain items is to be tested by Carnival Cruise Lines.

The trial will run on three ships from Sunday including chicken wings, fried shrimp, quesadillas, pizzas and sushi for an extra charge of between $4 and $7.

The new room service menu will be tested on the Carnival Imagination, Carnival Conquest and Carnival Pride and could expand to other ships if it is successful.

Carnival told USA Today that a wide range of room service items will still be available free of charge on the new menus.

“The expanded room service menu is designed to significantly broaden and upgrade the line’s culinary choices available for in-room delivery,” the line said.

“There continues to be a wide range of complimentary choices, and these new fee-based options are simply intended to create even greater choice and variety for our guests.”

The move follows Norwegian Cruise Line starting to test room service fees of between $4.95 and $7.95 for an expanded menu on two ships from last month.

Royal Caribbean International started charging for some room service items on new ship Quantum of the Seas last autumn and plans similar fees on sister ship Anthem of the Seas which is to sail from Southampton on its maiden season this summer.
