Have cruised with P&O since 2004, and can unhappily say that this cruise was the most disappointing and not up to the standards I expected.
On the plus side, it is still an advantage to have the flights included which means you don't have to collect your luggage at the arrival airport, you are taken straight from the plane to the port, next time you see your luggage is in your cabin, and on disembarkation day you stay on the ship until it's time to go to the airport. The Headliners theatre put on excellent entertainment as expected as did the live lounge, food in the main dining room was mostly of good quality, shore excursions were very good and very well organised, and individual staff on the ship were courteous and gave good service. There are laundry facilities on board so you can iron the travel creases out of your clothes
On the negative side there was clearly a cutback on the number of staff available in all departments
Cabin was as expected for an inside cabin, it was cleaned, towels refreshed and beds made once a day. THERE WAS TEA AND COFFEE MAKING FACILITIES AND ADEQUATE POWER SOCKETS
