Maybe it's not a threat. They may not all be here on CC, but there are people who will not cruise with Princess again because of this treatment and other shortcomings. I know some cheerleaders vigorously defend anything Princess does, but it is not the same cruise line it was in 2019. I don't blame the OP one bit for feeling Princess did not care about him or his wife. I was sick on a Princess ship some years before covid, and the medical staff, along with the crew, treated me with concern and care during my isolation. That was the old Princess.
Disclaimer for those who seem to think they need to know: Yes, I have two Princes cruises booked. Like several others, I am burning off the FCC. I let Princess keep my money (on a not-cheap cruise) during the pause, and I accepted the "good will" FCC they offered. Now we are down to the good will money and for my future Princess cruises I am going to spend their money.
