We did not use Princess insurance on our Alaskan cruise where we contracted Covid. Princess, however, had promised us FCC and, at the time, a daily food allowance as we were required to quarantine off the ship. After filling things out, and waiting 8 weeks, someone on CC said it was best to contact Princess Solutions. The thing was...you can't contact Princess Solutions directly...you have to go through Princess Customer Service.
So on a day when I had lots of time, I called the main Princess number. After being on hold for over a half hour, I spoke with a rep and asked to be transferred to Princess Solutions. Two & half hours later I finally spoke with a lovely woman and explained about our FCCs, covid, etc. After checking her records...of which there was not one for us...she explained that she needed to contact the ship to confirm we had test positive and had been quarantined. I also emailed her all of the documentation that I had. She asked that I give it 10-14 days. Two weeks later I emailed her to follow up and precisely two days later we had our FCCs and a check followed the following week.
It may definitely be worth your time to contact Princess Solutions. Oh, and when you get transferred to them and are on hold, it may seem like you have been disconnected. Just stay on the line. Best of luck.
