Princess Cruises is jumping on the Black Friday sale phenomenon with a series of discounts on ex-UK sailings.

The four-day promotion covers select departures from the UK to destinations including the Mediterranean, Scandinavia and Russia.

Further reduced rates are available for third and fourth passengers sharing a cabin.

The reduced rates start at £599 per person for two people on a seven-day Scandinavia cruise and £249pp for third and fourth berths

A 14-night Mediterranean cruise leads in at £899pp for two sharing and £399pp for third and fourth berths.

A 14-night Baltic voyage in August starts at £999pp for the first two people sharing and £499pp for third and fourth berths.

UK head of sales, Alex White, said: “This short sale offers fantastic pricing on a selection of our ex-UK 2015 voyages.

“With added savings for additional guests sharing a stateroom, now is a great time for agents to book a cruise for customers planning to travel with friends and family.”

P&O Cruises is also getting in on the Black Friday frenzy by offering extra onboard spending money for bookings made by midnight on Sunday in addition to an existing £50 low deposit offer.
