This offer applies to approximately 250 Carribean voyages on six different ships, from 1 December 2019 to 22 May 2021, writes Stella Bullock.

All main meals and a drinks package are included, as is up to $1,500 spending money onboard, depending on the cruise length and the type of stateroom.

The deal is on sale until the end of July.

Tony Roberts, vice-president of Princess Cruises UK and Europe, said: “With its white sands, year-round sunshine and crystal clear waters, the Caribbean remains a hot spot for returning and new-to-cruise guests.

"By taking advantage of this offer and allowing Princess to cover the drinks bill, our guests can raise a glass to this stunning part of the world as our ships cross its islands.”

Several ships are offering Caribbean sailings, departing from the port of Fort Lauderdale and lasting in the region of four to 21 days.

They feature calls in St Thomas, St Maarten, Cozumel, Aruba and Curacao.

Also included in the deal is the latest addition to the cruise line’s fleet, the 3,660-passenger Sky Princess once it has been inaugurated in October.
