There are a couple things i have noticed post-covid.
They skipped out on the towel art. I only got it 2 times in 3 cruises in my vista suite and I asked for it for the kids.
The main dining room has cut back on the silverware and glasses normal used for a MDR place setting. No salad fork, bread plate etc... I think it makes the experience less grand. The food has been a step down in quality in the MDR. I eat now in Club Orange mostly. They cut out the NY Strip steak option and only do it on occasion or you can get the $40 dry aged. I think it is a bunch of little things that combine to make the overall experience cheaper (for lack of a better word). If you hadn't cruised on HAL prior to COVID you probably wouldn't notice but if you had it is noticeable. I just think they made some cuts in areas that really don't save them a lot of money but impact the experience. I am getting on a ship tomorrow so I will update but in Nov it was the above... I would also say Club Orange is definately worth it.
