Off topic but we are cruising Dec 27 too. I was discussing with my PVP and he said I will have to take the covid test Saturday (which is Christmas) or Sunday (the day we are driving to the port). Have you thought about what you plan to do to get the covid test?
I, too, am sailing 12/27 on the Celebration. If we are up to date with vaccines, we can take the test 12/24 which is 3 days before we sail.
