I put "cruiser" in quotes above as one of the reasons for taking this trip was to experience the closest thing still available to taking a voyage on an ocean liner. Cunard likes to call it a crossing rather than a cruise and that is what we were after, as we prefer to avoid airports whenever possible.
We have never travelled overnight on anything larger than a trans-tasman car ferry so it was a real adventure for us.
Other than seeing this huge ship up close, the other aspect of the journey that appealed to us was the dressing up factor - there are not that many opportunities to 'dress to the nines' in our home city and dressing for dinner 8 nights in a row was a real treat. Even the informal dress code on QM2 requires a jacket for men and something fairly classy for women, so every evening meant a change of clothes and some selfies in the cabin before heading out for the evening.
We had booked a Britannia Club Balcony so had flexible meal times. The advantage of this was being able to arrange our evenings activities based on what we wanted to see. An early show in the Royal Court Theatre and then dinner or dinner then a late show or watch the dancing in the Queens Room.
The downside of the flexible meal times was that there were times we arrived at our table for six just as our fellow diners were finishing their meals. This seemed a little awkward and somewhat impolite at first but by the end of the crossing we were all quite comfortable with the comings and goings and in fact had gotten in sync a bit.
We went to several shows in the Royal Court theatre and enjoyed them immensely - including Apassionata which has apparently been running for a long time and viewed as a little tired by some frequent travellers. We liked it very much though and wouldn't hesitate to recommend it to new QM2 travellers.
During the day there were lectures in both the Royal Court and Illuminations theatres - A special highlight was Seth Gopin's series on New York skyscrapers, which provided us with a framework for exploring Manhattan after our crossing.
There was no shortage of organised activities and always the passing ocean to watch from a window in the Sir Samuels coffee bar or the Commodore Club. A pre-dinner "molecular martini" in the Commodore club was a real treat.
QM2 met our expectations and exceeded them in some areas. The Britannia Club dining room was excellent and we ate most meals there. We had one lunch and one (birthday) dinner in the Todd English restaurant and enjoyed it very much as well. A pub lunch in the Golden Lion was a nice change from the main dining room.
A few tips for the first timer on QM2.
If you plan to eat lunch at the Kings Court Buffet on the first day as the MDR is closed, go all the way through and you will probably find much less busy service areas and staff away from the "main" entrance. We did not venture back into Kings Court for the entire trip so cannot really review it.
The staircase to the side alleys (through the art gallery and the images (photos) gallery) that bypass the Britannia Restaurant is right next to the entrance to the Queens Room, NOT off the main staircase and not visible from the cross-ship corridor ... it took me days to get this right. It is plain on the deck plan but somehow I still didn't get it .... It is a big ship and can take some working out for those who can't hold 3D maps in their head.
If you have a with your stateroom, just ask your stateroom attendant or call the Purser. We put up with a weird noise in the aircon for several nights - one call to the Purser and it was fixed that day.
