We have had exactly the same happen to us as Sellavee. We didn’t even get notification. I phoned my TA to make sure all was OK a with our booking and when she contacted Regent that’s when we found out. I think Regent has behaved very badly. £200pp compensation is derisory-transfers alone will cost about £150 which leaves £250 for a hotel. In future I will book an F1 grade (which on this cruise was about £800pp cheaper) and arrange my own hotel and transfers, This is not our first Regent cruise, we are gold level, How did they decide who to ‘bump’. I can’t believe it’s every passenger that booked a concierge class cabin.
