So we are booked to sail on QM2 on 2nd June heading to Norway on cruise M415 and we just received our upgrade offers. When I last cruised with Cunard on a TA I don’t recall being offered the option of bidding for stateroom upgrades but for me it’s an interesting new wrinkle to the booking process. With that said they are offering various bids for upgrades including one to a Queens Grill (minimum bid £2,700 per couple max bid £6,300) and one into a Penthouse Suite (minimum bid £5,340 per couple max bid £12,460), so out of curiosity I looked at the website and Penthouse Suites show as sold out. Just wondering if anyone has the logic behind this, I get the logic behind upgrades in general but offering discounted rates for staterooms that are not available for full price reservations seems odd. Any thoughts on the logic, and also any thoughts on upgrading?
