It's done a complete about turn in roughly the last three or so years; in the past every dress code thread would feature the same bod who popped up with imaginary percentages of those wearing bow tie and others would chime in, sometimes quite unpleasantly, nearly always along the lines of "why choose P&O if you don't particularly like formal nights", completely overlooking the small point that, between them, in the not too distant past, P&O, Cunard and Fred Olsen, all of them featuring formality, were almost the only mainstream cruise lines to sail out of the UK. Plus, of course, as someone has already said so eloquently, there's a bit more to deciding on a holiday than one aspect that doesn't particularly appeal.
From memory Davecttr was one of the few brave enough to debate the subject from the other perspective; I certainly laid low.
