Fred Olsen Cruise Lines and Princess Cruises have both unveiled Black Friday deals to encourage bookings by November 30.
Discounts of up to 70% are being claimed by Fred Olsen, which has 12 cruises included in the sale including latest fleet additions Bolette and Borealis.
Princess is offering a week next August for a family of four from Southampton to the Norwegian fjords for less than £2,000.
Eleven of the 14 Princess cruises included in the promotion are returns from Southampton by Regal Princess to destinations across Europe and the Mediterranean.
The other three are 12-night round-Britain sailings on 3,660-passenger Sky Princess leading in a £999 per person.
Fred Olsen Cruise Lines sales and marketing director Jackie Martin said: “2020 has left us all dreaming of our holidays, and we can’t wait to get our ships back in service next spring.
“Black Friday has become such a popular event in the UK, and it is a great opportunity for us to be able to showcase some of our 2021 cruises while offering our guests the chance to make some great savings.”
Passengers with Princess can choose upgrade to all-inclusive ‘Princess Plus’ fares, including premium drinks, Wi-Fi and tips for gratuities for £35pp per day.
This means a seven-night all-inclusive cruise in the summer holidays starts at £944pp based on two sharing, or under £3,000 for a family of four.
UK and Europe vice president Tony Roberts said: “We are delighted to once again offer our guests great value through our Black Friday deals, with a week’s holiday from the UK in peak season available for less than £2,000 for a family of four.
“With a range of destinations and two fare options to choose from, guests should be able to tailor their perfect summer holiday to look forward to next year.”
