My husband and I choose to travel to NY each year on the QM2 (and have done for the past 11 years and beforehand on the QE2)as we do not like the hassle of flying, although we do fly home. We consider the QM2 liner gives you 5 star accommodation for 7 days, with complete relaxation. The food and service is good. If you do have a problem in the Restaurant, all you have to do, is report such problem to the Restaurant Manager when he will deal with things promptly.
This last May trip; unfortunately slightly different, as we experienced fog most of the way and the ships whistle was going day and night. As I said to one passenger, who was complaining, isn't better to be safe and have the whistle going, than hit something that the radar doesn't pick up.
If you check, with the ships brochure and Agent, that you haven't got a blocked vision, when booking a balcony, then you should not have any problem. Deck 8 has all the lifeboats on - so one has to be careful to avoid some of the staterooms on this deck.
This is the only liner that carries pets across the Atlantic - so one has to be aware of certain walking times for dogs on deck 12.
We really enjoy our weeks holiday on the ship before we arrive in New York and you can meet some very nice passengers. I always look forward to our time on the QM2.
