Ah, why not say so?
I just don’t see a difference, or certainly no more than the difference between QM2 and the Vistas. I don’t think I have a nose for the essence of Cunard that so many people miss, though I seem to remember many similar comments when QV, in particular, was introduced. I would choose the Vistas over her, firstly because of the Grills Lounge (and Courtyard) and also simply because they are smaller and easier to move around, and, particularly, because it is less of an expedition to each the Library, though the view when you get there is much better on QA. I also think, with a few obvious exceptions, QA is a much more beautiful ship on the inside.
Anyway, I must practice my howling for next year.
