I worked traffic control for the cruise prior to ours (we're sailing Jan 6th too - I think you mean 2023 not 2022). I was expecting the worst since they are at near capacity. It went surprisingly well. A little before 11am, they were already calling elite and suites to begin boarding. About 15 minutes later, the next group (platinum maybe? I didn't hear the announcement) was allowed to board. (Yes, I snuck into the terminal to get warm - it was freezing outside). Then again, the prior cruise was at around 50% capacity, so probably a quicker turnaround.
