Myself and my partner booked our cruise last minute, and it was by pure chance that we found ourselves on P&O's Oceana. We chose a balcony cabin, and were lucky to be on quite a high up deck. The stateroom was just big enough, well furnished and comfortable. The balcony was lovely, we would sit on it for hours watching the sea go by!!
The food in the main dining room was on par with a good 4* restaurant, and all the waiters were very polite and nice. Breakfast in the Buffet was OK, and we only realised on the last morning you could have a formal breakfast in the restaurant doh!!
We frequented the casino, which was a bit on the small side but fun. (slot machines from an bygone era that actually spat out coins when you won!!)
Overall we loved every minute, and were very impressed with the overall running of the ship.
We have booked another cruise already, but are going to try Celebrity again just because a good deal came up!!
