P&O Cruises is offering two world cruises for 2015, collectively visiting 69 unique destinations in 38 different countries and covering 61,470 nautical miles.

Arcadia is sailing a 106-night full World Circumnavigation exclusively for adults with single cabins available, and Aurora is sailing a 105-night South America and Pacific Adventure for families, couples and solo travellers alike. Both sail roundtrip from Southampton.

The world cruises are available for pre-registration from Wednesday August 21, 2013 on line, by phone or through your travel agent, and go on general sale Thursday September 5, 2013.

At 106 nights with lead-in Vantage Fares from £9,999 per person, Arcadia’s cruise is a classic full world circumnavigation. Exclusively for adults, the destination and port-rich cruise features five maiden calls for Arcadia to Bitung (Indonesia), Darwin (Australia), Lahaina (Maui, Hawaiian Islands), Manila (Philippines) and Sanya (Hainan, China).

Arcadia also features extended calls in San Francisco, Honolulu, Sydney, Hong Kong, Dubai, Safaga and Sokhna (Egypt) to enable passengers to enjoy once-in-a-lifetime experiences in these ports – from tours of ancient civilisations visiting lavish tombs, temples and palaces in Egypt, to the hustle and bustle of modern day city life in Hong Kong.

Aurora’s 105-night South America and Pacific Adventure is family friendly with more time spent in New Zealand, including a cruise through its famed Milford Sound. The cruise features three maiden calls for Aurora to Akaroa (New Zealand), Rarotonga (Cook Islands) and Moorea (French Polynesia). Lead-in Vantage Fares for this cruise start from £9,299 per person.

Extended calls on Aurora will be in Rio de Janeiro, Montevideo, Sydney and San Francisco so passengers can take in these cities’ breathtaking sights during the day as well as into the night.

P&O Cruises managing director Carol Marlow said: “A world cruise offers so much more than an extended holiday, it’s an experience of a lifetime, an adventure on an epic scale. How else can you visit so many destinations around the globe, enjoy a whole host of once-in-a-lifetime experiences and immerse yourself in new cultures, countries and sights while travelling in consistent style and comfort?

“Our two world cruises for 2015 are no exception and offer excellent value for money. With prices from £89 per person, per night for our South America and Pacific Adventure on Aurora, it’s a fantastic way to see the world without having to compromise on home comforts.

Booking early also means passengers receive the best value, with our Price Promise protection, and they can enjoy all the benefits that booking early affords, such as being able to secure their preferred choice of cabin and dining option.”
