We have been on a number of cruises previously, on each occasion aboard "traditional" ships which are much smaller than Azura and all her other practically identical floating leviathans.
Let me start by saying that P+O did everything they claimed to do. Food was good, entertainment was very good indeed although sometimes not to our taste. The cabin exceeded expectations and no complaints at all about the service.............
........BUT............
All cabins on D deck seem to be pretty similar. Ours was towards the rear of the ship and if the person next door had not been stinking us out with his cigars, would have been superb.
The more expensive cabins are closer to the centre of the ship but they are the same in terms of accommodation and get far more noise from the knees up that happen on the top decks as the ship leaves a port.
Movement of the ship was not a problem for us at the rear of the ship and our cabin had the added benefit of being just across the corridor from the passengers' launderette.
