Editor's note: This ship is no longer sailing as part of the P&O fleet.
This 2,016-passenger ship joined P&O Cruises in 2003 after switching over from Princess Cruises, where she had been in service as Ocean Princess since 2000. A makeover in 2012 updated the vessel: the informal burger joint, Beach House, was added on the sun deck, and Le Club was transformed into a multipurpose venue for lectures, craft classes, and a nighttime disco.
Now one of the most popular ships in the P&O fleet, Oceana has an informal atmosphere that makes it particularly attractive to families. On this vessel, you can dine anytime you want in the main dining rooms, or see kids playing Marco Polo in one of the three pools.
