Double on board spending money is being offered by P&O Cruises to encourage bookings until next month.
The offer applies to selected Spain, Portugal or Canary Islands itineraries when booked by September 4.
The offer covers new Select Price bookings made on applicable holidays of 12 nights or more.
Extra on board spending money can be used against a variety of experiences including dining in speciality restaurants, spa treatments or shore excursions.
For example, a 14-night itinerary on Iona from Southampton to Madeira and the Canary Islands departing on March 15, 2024 leads in at £1,199 per person with £640 on board spend under the promotion.
A company spokesperson said: “The summer holidays are a chance to enjoy fun in the sun and during July and August P&O Cruises has offered double on board spending money to a variety of warm destinations so that guests can look forward to next year’s summer getaway.”
