Other reviews that you read are "spot on" so we won't repeat or duplicate totally.
It was so very sad. There is a lot of attention paid to pretentious formal dress (which is/was fine - we have all of the necessary clothes and jewelry), but nothing much parallels that environment. The food was pedestrian - under/over cooked - serving sizes our watier apologized for - service was slow - one night we waited 40 minutes for our starter.
The enrichment lectures/movies/plantarium are wonderful.
Service at the King's Court was unreal - waiters in the way - ice cream machines that worked intermittingly - coffee/cup layout that had little or no traffic pattern.
Other side things - I had a spa appointment and the stylist told me when I inquired that tips weren't included - they were.
I have a high level contact in Carnival Lines (owner of Cunard) and we did receive a follow-up phone call but clearly she had "drank the kool-aid" or just came from customer service trainging because the call did not express geniune concern for the issues we addressed at all - just keep saying - yes, we understand......
Cuanrd now has competition - great cruise lines like Holland and Celebrity who serve wonderful food and even if you're in a suite or steerage - you truly are treated the same ship wide.
Disembarking was a diaster with no porters - some kind of union walk-out on the docks - but Cunard had no grasp of the issue and it was chaos until the union personnel walked back on - no back-up plan - a diaster.
If you want transportation and the basics - this is a great trip - if you want true cruise experience go Holland or Celebrity - and have less angst and no matter what consistenet service.
