We took the Queen Mary 2 across from Southampton to New York in December 2013. Our package included 2 nights in New York as well as all flights and transfers: a really good deal. It certainly lived up to our expectations.
Check-in was well organised, given that they had over 2000 to check in in a very short time. Once on board we easily found our stateroom: a balcony on deck 11. A good size and well equipped, including toiletries, bathrobes, slippers, TV and safe. Plenty of storage space. Very clean and our cabin steward could not have been more helpful.
It takes a while to get used to where everything is but there is plenty to do on board: talks, entertainment, dances, a superb library and a not-to-be-missed planetarium. Or you can simply chill in one of the bars/cafes. There are also several swimming pools, but these were closed due to the bad weather.
Good size with plenty of storage space. Well equipped, including toiletries, bathrobes, slippers, TV and safe. The bed was extremely comfortable. Very clean and our cabin steward could not have been more helpful. Having seen some of the 'better' cabins, I would not bother to pay more for them: how much space do you need.
