I don't know about Norweigian Air, but our British Airways flight from Rome to Heathrow on the 12th went just fine. Their terminal on both ends was very quiet. I was worried they wouldn't have their planes in place after the two day pilot strike on the 9th and 10th, but all went well for us.
Aside from the detour, we had a wonderful cruise. The worst night was when they turned south in the middle of the Atlantic.....that was a very rough night. The next day the captain announced that it would be worse....but turned out much better.
We, too, only had a bar of soap in the toilet bathroom sink, not the shower room sink. I just left a note for our stateroom host and he took care of it. I assume they are trying to cut back on waste, but I bring coffee back to our room in the morning and need to wash up and its convenient to have that second sink with soap when someone is using the other area.
Regarding the theft of items from doors and the the fish clip.....was it reported to security? There are cameras in the hallways and other areas. We had a nice conversation with the head of security....retired law enforcement from the UK. I'm curious if it was reported and if they did anything about it. I found something on our fish clip....a rolled up paper that said "pixie dust" on the outside, and it turned out to be a typewritten recipe for snickerdoodle cookies. We did not belong to any "group" and figured it was put there by mistake, so I put it back there, but it stayed.
The adult pool was also closed many times. It would be open in the morning, but then would be closed a few hours later when the seas got rougher. It got downright dangerous to be in the pool. My main complaint was the same people sitting in the hottub for hours....no room for anyone else and the other hottub would be packed, but at least people got in and out.
Most of our meals were good. I need to remember that I am not eating at Narcooses or California grill, but in MDR on a cruise ship that is pumping out hundreds of meals. I learned early on that the beef needed to be ordered medium rare, and I would repeat that to my server....the dining rooms are quite loud. I sent back my beef the first night....it was closer to well done. I thoroughly enjoyed the appetizers and soups.
I was a little disappointed with the lack of communication regarding what was going to happen at Ringskadiddy port. We did not attend the show the night before and had no idea they were supplying shuttle busses to town. Someone on deck 10 that was also enjoying the ship entering the harbor in Cobh told me about it (they attended the show and they announced it there). I had checked the paper navigator over and over and saw nothing. Should have gone to guest services to ask I guess. Maybe I missed it on the navigator. Either way, was happy about the shuttle and we had a nice day.
