This was our big concern before going on our cruise last month. We love DCL so much and have sailed 16 times before, so we did not want to go back until the cruise was close to normal. It was WONDERFUL. For the most part it felt very normal. There are a few things like the above posts mentioned - we actually liked Cabanas for dinner, but since this was our first cruise back in 2 years we did not want to miss the MDR, so we didn't even know this was missing.
The things that did stand out for us:
1. No future cruise desk - instead there was a sad empty desk and some random cords and screens sticking out (this was an eye sore and looked so out of place). This may never come back though as they are pushing for placeholders.
2. No menus handed out at dinner - but on our last day we were told we could have asked for them and did see other families get them, so this is available just not standard procedure. We have a no phone rule during dinner, so going on your phone to look at the menu violated this (as our family kept telling us
3. Character meet and greets - people had to stand on a dot; but this is changing this week back to normal
4. Masks - we haven't worn masks in a long time, and seeing staff wearing them just felt so weird - this was the hardest thing for us and only thing that really felt like the cruise wasn't 100% normal yet. We live in East Tennessee and mask wearing is minimal. Seeing the crew wearing them while talking to us takes you out of that magical DCL feeling that you really feel like you are away from the world. Our cruise was the first in which they ended their policy of having to wear masks while working at Castaway Cay and outside on the ship - the crew was so happy and it was so nice to see the smiling faces of everyone. No idea when this will change for inside staff and close contact staff.
But it was a magical trip and we have 2 more cruises next month. I would say it is very close to normal now, and the last real bit is the inside wearing of masks for the staff. I think though in some parts of the country and world this is more normal for some people (as I said we live in TN so it is odd for us).
