You will however be compensated for the missed day, so you will still be getting a 14 night cruise for the cost of 13 nights plus 2 x $50.
While you think it is okay to put words in my mouth please don't, I NEVER said I begrudge the $50, I have spent a lot on my holiday so doesn't bother me, however I do think (as I actually said) I am surprised by the generosity of Cunard.
