We had cruised on this ship to Norway , late in the year, and found it cool on the ship and cold in the fjords. Still it was easily the best and most economical way to see them, We researched flight and ferry options as well as hotels and all worked out at least twice as costly and without the views from the 10th deck of QE.
We knew the Med - from Venice via Dubrovnik, Piraeus, Kusadasi, Greek Islands and Sicily to Civitavecchia would be different. And it was. Knowing the ship already was helpful as we paid a bit extra for a balcony cabin so that we could open a window and avoid being blown away by the aircon. The drawback was that the few smokers on Cunard are now addicts and chain-smoke on their balcony from before dawn untikl midnight or later. When they do, the smoke is sucked straight into your cabin and there is nothing for it but to close the window. From May 2014 QE balconies will be smoke-free and the problem should evaporate.
The QE aircon seems to circulate germs and if you sit for long in a cabin with the windiows shut , you are likely soon to be sneezing and coughing. We noted many of the Japanese passengers wearing face masks, which is what they do when they have an infection.
