I Suppose you get what you pay for.
Our experience of cruising is limited and entirely related to late booking saver fares involving allocated interior cabins. Presumably, any responses to complaints (and any sympathy) is likely to be viewed on that basis. However, our previous two cruises were with Cunard (QM2 and QV) on these arrangements and we would rate both of these as excellent. These cruises are, therefore, our benchmark and we approached our first P&O cruise expecting something similar (we paid slightly more, on a per day basis, than on the Cunard cruises).
Firstly, there were some positives. The Oceana is a comfortable, clean and generally attractive ship, comparable, in many ways, to the Cunard QV. The embarkation procedures were highly efficient and the allocated cabin was exactly what we expected. The Cabin steward was a smiling, friendly and efficient young man on his first cruise. The itinerary was attractive and the weather was fine. The staff was generally polite and friendly and the entertainment was generally very good (Vernon Lewis was outstanding).
