I received the exact same email and was planning on showing up untested and providing the email as proof. Then I called Princess to double check and was told that was a mass email sent out and did not apply because we were going to Greece. I asked what would happen if I showed up untested and was told I would not be allowed on the ship even though I had this email saying I did not need to be. So just to be safe, I am now going to be tested. I suggested they are going to have many unhappy passengers at the port and that they issue a correction, but nothing has been done yet. What a mess, Princess needs to get their act together.
