We travelled in QM2 for a short 10-day leg of the ship's current world cruise, taking advantage of a generous sale that had been advertised. In short, the experience was everything we expected, and more.
Every aspect of the ship's service was of a very high standard. Crew members, waiters and cabin stewards quickly got to know our preferences and routines, and provided personalised service to match. Our balcony cabin was about the usual size for a cruise ship cabin of that standard, but was well designed and comfortable.
Despite some review suggesting otherwise, we found the quality of the food in all locations to be excellent. The main dining room (Britannia) provided a varied menu of high-quality dishes. The buffet (King's Court) had a good variety of excellent food, and we were especially impressed with the 'alternative dining option', "Bamboo", which is well-worth the additional charge. We also dined at The Veranda Restaurant, for one meal. While this was also exceptional, we doubted whether it was really worth paying the significant surcharge for this restaurant, given the quality of food and service at the other locations.
Comfortable and spacious enough for two people. Plenty of storage. The 'sheltered' balcony has limited use, given that you can't see anything (Other than the sky) if sitting on the provided lounges, but still allows for fresh air into the cabin, and a quite, private retreat.
