We have paid just over 6k for 2 weeks in a balcony cabin including the upgraded drinks package and airport meet and greet parking, so all we have to take is spending money, but one thing that swung it for us is the itinerary, we have been to all of the islands visited by P&O many times, but only 1 on the Marella cruise, Guatemala, and also the size of the ship, but whichever you choose, I am sure you will have a fabulous time.
