Good point 1: The ship is child-free.
We have done the Xmas caribbean cruise for the last 16 years and the last 7 years with P&O alternating between Aurora and Orians and can thoroughly recommend it. Although there are normally between 200 - 300 children on board you would never realise it as you hardly ever see them - however Xmas 2009 to the Caribbean is on Arcadia ( adult only ship ) and although we shall be on it I think we shall miss the little ones because they are what Xmas is all about.
Hi, I've done a Christmas cruise on both the Aurora and the Oriana and can thoroughly recommend it. We were at sea on Christmas Day on both occasions and the highlights were the morning carol service, the lunchtime pub singalong and the evening dinner. On Christmas Eve Santa boarded the ship and climbed the funnel and Christmas presents from the captain were delivered to each cabin. I hope you have a great time.
