We had traveled several times on Princess, and once on Royal Caribbean. My wife always longed to go on the QM2, and we finally decided to "try the best" so we took a July 4th New England Cruise out of New York.
First the positives. The ship was clean, nice looking and our waiter and steward were very nice. The ports we visited were good. Plenty of deck chairs, and the ship never seemed crowded like all of the others we had traveled on. Great internet services, and good activities. There were two "balls" which were both very nice and well executed. The ship is a beautiful ship and looks awesome from afar.
Now the negatives. We really did expect a "step up" from the Princess vessels we had been on, that may have been our first problem. Our cabin was clean, with the exception of an 8" stain in the middle of the carpet.
