My wife and I just arrived home from the same cruise, so I will add a little of our experience. First I would like to say to the OP that I am so sorry that your cruise turned out the way it did, I do not feel that you were complaining, just telling it the way it was. My wife and I had an inside room it was very nice, but I could not image being quarantined in it for 5 days. I think I will be upping my bid on the next cruise.
We arrived at the cruise port at 12:15 and boarded the ship within 30 minutes. At the end of the cruise we did 'walk off'. I was the smoothest we ever had, off the ship and picking up our car at the hotel by 7:45. I totally believe the OP's bad experience, this just shows how 2 different people can have a different experience on the same cruise, just luck of the draw.
The only really negative for us was my time dining, we tried to book a time on the app before the cruise but could only get 5 or 8 o'clock, we tried to book on the ship and same thing. The second night we tried to get a pager about 7 and were told it would be an hour so we may as well wait until 8. At that point we gave up on my time and asked to be moved to 8 o'clock regular dining. They gave us an excellent table for 2 by a window. Our waiters and food were very good. The regular dining room seemed to be half empty many nights at 8, the my time seemed overwhelmed. Why not just make the whole dining room my time? (just my opinion)
It was also our anniversary on this cruise (38th). We booked the Tuscan grill, the food was good, better than the dining room but we did not think it worth the extra money.
We thought the Ship was in good shape, and the crew worked hard, but I agree they seemed to be
short staffed. Sorry I did not mean to high jack this thread I was going to write a review but just thought i could add our comments here.
