Have cruised with Celebrity, R Caribbean, Costa and Princess, so have some reference points - ship is a bit tired, passengers almost entirely Brits, and although my wife and I had a great holiday, the frills were definitely missing.
Some good points - smooth crossing and reasonable weather; main dining room food and service excellent; usual stuff like newsletter of daily activities provided and quite a lot to do (essential of course for transatlantic) Lots of minor reservations on quality - self service food choice limited; speciality restaurant not impressive - more of a bistro; entertainment patchy in quality, and choreography/costumes for shows not up to competitors; staff attentive but glum; room service limited, often with extra charges; some localised maintenance lacking such as torn seats, toilet fittings and lights not operational, rusty spots on bulkheads on balcony, unvarnished handrails Just to add to things, there was a norovirus outbreak on board, with rigorous quarantine and sterilisation programmes from day one - all passengers in affected cabins (not just ill person)strictly quarantined to cabin for days - self service closed for several days. Anyone who had to visit the ship`s doctor was quick to express surprise at the level of (immediate)charges, and sometimes also the overzealous diagosis/treatment. This is not necessarily a criticism - better safe than sorry - but be aware. Computer system broke down for boarding, so long queues in a warehouse in the heat, after a wait in the bus due to multiple simultaneous flight arrivals. Balcony limited in size and is hole in bulkhead rather than glass like more modern ships.
