We did B2B on Millennium (Alaska) May 13 and May 20. Not until our first week onboard did we learn definitively that there would be no testing required for the second week's journey. Whew!
Just a few days ago, during our second week, the captain announced that he was required to notify us that 2% of the people onboard had tested positive for Covid, everyone was encouraged to be extra diligent about hygiene, and masks would be required in the theater. That was the first and only information provided about Covid cases. It was interesting that as the week went on I noticed ever more passengers wearing masks - but they remained a small proportion of the people onboard.
