Nearly 200 cruise passengers were awarded several hundred thousand pounds payout after illness spread across the ship.
Passengers complained that the toilets on the ship were blocked and food was served lukewarm.
Elizabeth Tetzner, a travel law expert, said: "A number of the passengers that suffered illness suffered from symptoms such as stomach cramps, diarrhoea, vomiting and lethargy."
The pay-out relates to a period between December 2009 and June 2010 with destinations including Morocco, Gibraltar and Las Palmas.
Collette Ellis from Fareham in Hampshire booked a two-week cruise to celebrate Christmas but her holiday was ruined by the illness suffered onboard.
We are happy that we have received justice after our holiday wastotally ruined. The conditions aboard the vessel were atrocious. On occasions toilets wereblocked and overflowing, cabins were grubby and on occasions food was not servedat the correct temperature. This was supposed to be a dream cruise but it quickly turned into an absolute nightmare, certainly a Christmas time we wanted to forget. On our return home both myself and my mum, who was celebrating her 75th birthday continued to suffer illness. We are just glad it's over for us now and we can move on with our lives."
