We were really looking forward to our cruise because it had been four years since our last cruise but due to a family bereavement and Covid, this was our first since then.
The staff were amazing especially the waiters and buffet crew although some passengers thought there was nothing wrong in asking a bar waiter to walk a few hundred yards to get them a coffee from the buffet. Some people should give the P&O stewards a bit more respect - they are not servants.
The My Holiday app was a hit and miss affair. Even though my wife was linked to my account, if she booked an event, it didn't show up on my account. At the start of the cruise it was difficult to book a show because they were all fully booked in advance by other passengers. Some I think had booked both slots (first / second show) to give themselves a choice and didn't bother cancelling the other slot or if they didn't attend, didn't cancel their booking. Due to late cancellations of some of the artists, replacement artists came on board which freed up some of the show booking slots. The entertainment was nowhere near the quality we have seen on previous cruises. Many of the acts were tailored for the older generation, we are in our 60's and it seemed even too old for us. Also P&O used to have acts that did tribute acts for one artist, e.g., Elton John and another act would sing Dusty Springfield songs. Unfortunately, there were a few acts where one artist would sing Dust Sprinfield on one night and then perform songs from another artist on another night which meant the quality was a watered down affair and the quality of the act was somewhat less than previous cruises.
The cabin was good but the air conditioning was awful. I developed a throat infection four days into the cruise (I tested clear on the 6th day) and the air con made my condition far worse and last longer.
Philip the Cabin Steward was excellent however and went the extra mile to meet our needs.
