For our round UK cruise, the booking blurb said Q1-4 would have priority tendering. We didn’t get our tickets. When I remonstrated, Sandra, the wonderful Concierge, said it was now only Q1-2, but they would of course honour what it said. The tender tickets duly arrived, but I had Covid, so didn’t use them. I wonder how many other Q3s and Q4s didn’t get them at all. The latest brochure still says priority tendering for Q1-4. So booking blurbs aren’t terribly reliable, unless you are on the ball.
