I was a bit worried after our recent experience with Holland America, but thankfully P&O haven't let standards slip too far trying to make up some money after not being able to sail during lockdowns.
Sure, there were a few "fee only" items, and some things on the menu that you paid for in the complimentary restaurants, but on the whole everything was roughly the same as before.
The food was good overall, with plenty of variety. The breakfast menu in the Waterfront was always the same, but lunch and dinner were different (not the same thing night after night, yippee!). There was also variety in the Pantry.
10210 - nice and quiet. Only suitable for two.
