Cruise holidays are going to be bigger than ever in 2015, with new and exciting launches galore - and there are some amazing deals to be snapped up, particularly if you book in good time.

Whether you're a seasoned cruiser or a first timer, there's plenty to get excited about. For a start, P&O is launching a brand new cruise ship, Britannia - the biggest cruise ship ever built for the British market and featuring the first British cookery school at sea, run by celeb chef James Martin.

Then there's Royal Caribbean's Anthem of the Seas, due to set sail from the UK in November. The sister ship to Quantum of the Seas will feature everything you never even dreamed you could do on a cruise, from bumper car rides, roller skating and even a circus school to keep you entertained.

Meanwhile, river cruise specialists Viking are unveiling their first ocean cruise ships, with the first of their three ocean ships starts sailing from Norway in May.

We asked Liz Jarvis, Editor of Cruise International, to select some of the best cruises for the year ahead.
