I had the time of my life on the Queen Mary 2. She is elegant and beautifully decorated, with an Art Deco theme which reflects the original Queen Mary: walnut veneers and etched frosted glass, artwork throughout, and cased mementos of Cunard liners past and present. Glassware, tableware and bedding are all of high quality.
Service and food in the Britannia Restaurant were good, and I ate most of my meals there. I did eat in the self-service King's Court a few times; there is a good choice of food but many passengers push and elbow others out of the way. I even had my things moved to one side by people who wanted my table.
There is a wide variety of entertainment and I was kept interested and amused for the two weeks of my voyage, and didn't hear any criticisms other than that some people were unable to get a good seat for more popular events. I booked a city tour of New York, good value but it set off at 8am on a Sunday morning, and the city that never sleeps hadn't woken up.
I booked a standard inside as outside view cabins were sold out, but quite satisfied as the cabin was comfortable and contained everything I needed. The steward (Henry) cleaned and provided fresh towels twice a day.
