Our first cruise on Britannia but done many with P&O.
This is a lovely ship. Although big and lots of passengers, there is plenty of room and a good flow of people. Nice contemporary decor and cabins. The best flow of passengers I have seen in a ships buffet restaurant. Never had to wait or share a table even at prime dining times. Good service and food in the MDR. 3 nice big pools including the adult only quiet Serenity pool. Plenty of good quality sunbeds, although set out very close to each other.
Now! The public rooms were under employed most of the time. Headliners shows or guest act as normal in the main theatre each evening, but not much else on offer. The large Crystal room had a dance band playing sometimes, with just a few people watching or dancing, but mostly empty! What a waste of a good venue! The Live Lounge advertised all sorts of appealing music, but most of it was just a blank stage and recorded music. Another hugely wasted venue. Where was the alternative to the Theatre evening shows? Comedians, singers, guest bands? This venue was also completely badly designed. All on one level with dividing walls 4ft high everywhere blocking any view. In general, except for the Headliners and ships live bands the entertainment was scatty, boring and poorly arranged.
Cabin size comparable to other P&O ships. Nice contemporary decor and well set out. Good size shower with a proper glass screen. Well looked after by the steward. Large interactive TV. Good storage, and open closet. Be warned some cabins are a long walk from the lifts!
