Just back from a 7 day to the Norwegian fjords. First time with P&O but we have cruised with several cruislines, so we have something to compare them with.
Embarkation - long queues, unavoidable when 1800 people are boarding, but they dealt very efficiently with everyone.
Cabin - very well designed. Loads of storage, in fact I didn't use some of the drawers. Adequate number of hangers. Just one glass bedside the small fridge so I asked the cabin steward for a second one. He said that wasn't his department and I should phone room service. I also requested ice for our ice bucket (thick dust on top of it). I'm still waiting. Balcony furniture ancient and cushions badly stained. Hubby dropped his cruisecard down the side of the sofa so we pulled off the cushions to look for it. Yukk ! Food scraps - it hadn't been cleaned in a long time. Similarly, a pull-out surface just under the fridge for pouring drinks etc - thick with crumbs. I passed a steward in the corridor who was putting glasses into cabins and I asked him for one. He said no !! Said I would need to get one from my own steward !!
