My wife and I just returned from a combined eastbound transatlantic, Norway (14 days), and westbound transatlantic trip for a total of 28 days. This was our 19th voyage with Cunard and 44th cruise overall. We have cruised on the QM2 10 times in the past and unfortunately the quality of the cruises have declined over time. As one cruiser quipped the " QM2 has been Carnivalized."
The ship itself is still great with plenty of room, even with a full ship. Its four sets of stairs and elevator banks make moving about the ship easy. The ship handles the seas of the North Atlantic with the aplomb of the great lady she is.
But a lot of little things have shown declines in quality over the years. The toilet paper and tissues in the staterooms are now below that found in the restrooms at Walmart. The paper towels in the public restrooms are smaller in size and disintegrate when moistened. (whatever happened to the clot towels of yesteryear.)
We normally have an outside cabin for the transatlantic cruises because there is not much to see. We got this obstructed view cabin at the same price as an outside. The cabin was roomy with plenty of storage. Our only complaints ares the water flow has been reduced in the shower and is a little weak and and interactive tv would be nice.
