While I will have a similar situation in Jan 2023 - and intentionally have two different cabins, I think there's a 'wrinkle' that no one has covered. As far as I know b2b still requires a covid test - which as far as my TA and Princess docs specify, means a day or so before Princess will administer the test. If positive, I assume we would be removed from the ship (with all of our luggage) and not be allowed to return on the next leg of our journey. Since I'm booked on the world cruise as the 2nd leg, sure hoping that's not still going to be the procedure come January.....
