Our crossing on the Queen Mary 2 proved to be one of the loveliest travel experiences my partner and I have had - and we travel a lot, to destinations both traditional and off the beaten path.
Critics (and Cunard seems to attract a very steady stream of customers who are both repeat visitors and fiercely critical!) may carp, but in our seven days, we had consistently good to excellent service, food that regularly met or exceeded our high expectations, and activities that were on the whole highly enjoyable.
We traveled Britannia Club and will plan to do so again. The dining plan is the main attraction - open seating at the same table for all three meals, additional a la carte choices on the menu, and the same servers throughout. We lucked into a very congenial table for eight, and we really enjoyed the cosier atmosphere and more personal service in BC (we ate a couple of meals in the main Britannia room as well - fine, but not as polished). The additional menu choices (especially the excellent scallops) were much appreciated, as were the dramatic tableside dessert flambes. Highlights of the food included first-rate fish and seafood, and very good and unusual starters (in portions small enough one needn't feel guilty about have two - or more!). Soups were a disappointment, generally, and only once was there something we had to send back (tough, dry calve's liver).
Standard AA cabin at the end of the corridor, next to the Pavilion Pool. Nice having a neighbor on only one side, and no noise issues from the adjoining pool/pantry/bar area. Balcony is very slightly overlooked from the nearby deck area, but not a problem on our trip.
