We went on a family holiday on the Oceana and understood when we booked that it would be busy and full of children.
However, the marketing did not live up to the experience - the ship was dated, cabins cramped, poor in cabin entertainment, small balcony, very tiny bathroom.
Evening entertainment varied in quality - some good some bad and some very bad indeed. The main pool area resembled Butlins on Sea - luckily we found a quieter pool area at the front.
The Marco Pierre Restaurant was a huge disappointment - the location is in the middle a thoroughfare and the breakfast/lunch management unwelcoming and offhand. The menu was unexciting and the beverage service took for ever - suggest a dispense bar a bit nearer to the restaurant.
However, the Adriatic service staff, Peter and William, were superb - true professionals and Fernando in Magnums Bar was a true delight. The qualilty of the food was very good and the beverage prices very reasonable.
I would avoid The Plaza Buffet restaurant - it was a bun fight with people jostling and almost fighting to get the the counters - it wasn't as if they were starving. It was very hot and the smell of food was very off putting.
Another positive was the attitude of the cabin staff - nothing too much trouble - but don't expect any bathroom treats - only the basics.
Long queues for tenders to and from St Peter's port and long queues for coaches to towns - did not feel it was right that a 75 year old had to stand for a 1/2 hour trip into La Rochelle - not enough seats on the coaches provided.
Having cruised with Cunard before I would never travel with P&O again, the product and the experience have totally put me off P&O.
