We have just returned on the QM2 two-way transatlantic. It was brilliant.
I had read negative reviews, but should have just kept an open mind.
Perfect, not, but as good as... and life is too short to get too concerned.
If something is wrong, bring it up so it can be resolved there and then.
The stateroom was great, lots of storage space etc., a fridge was a bonus, lovely food everywhere, superb, friendly and very courteous staff, an amazing Steward, Afternoon Tea, a varierty of entertainments, super facilities, and the list goes on... Also amazing value for money I think, if you reflect on what you get.
I especially enjoyed the lectures and the Cunard Radio! ( No ads, chat, news - bliss. ) And the sea views!
( The only negative was the lack of taxies in the Taxi Queue at NY. We waited an hour. Others I discovered used Uber - top tip! Perhaps it's not a natural location for 'passing trade'. )
The QM2 really is a stunning ocean liner. We had some 'weather' but it really was very stable.
9.9 out of 10.
