Well, several things, but the main problem was that our cabin smelled like a sewer.

So did my wife's mother's cabin. Since it was a birthday cruise for her, we focused on her needs. She was seriously unhappy with the smell and the construction going on in the room across from her. She naps in the afternoon and couldn't rest with all the construction noise. They also shampooed her carpet and it was "soaking wet" as she put it and that upset her. She was really dissatisfied with the response from the guest services staff, but they did move her on the second day (of a four day cruise).
We did let them know about our cabin (we were on the exact opposite side of the "wall" from her) but they said there wasn't any thing they could do. The person to whom my wife spoke was pretty brusque and she felt rude, so that didn't help. She felt that the person thought she was trying to get something for nothing which wasn't the case. She simply wanted them to make the stink go away. So we ended up staying out of our cabin as much as possible, including showering in the spa. We slept there of course, but both ended up with three day headaches...
Friends of ours had champagne, cheese and fruit, pastries and flowers sent to our cabin. They also gave us shipboard credit and credits for the spa, along with purchasing Mickey and Minnie plushes.
We did finally receive everything but the spa credits... not too sure whatever really happened to those. We did receive a call from the spa saying we had credits (on the second day) so we went there, but once there they said they had no idea what we were talking about, and that they didn't do "credits."

Since we had no idea that our friends had done this we didn't pursue it.
There was more confusion surrounding all the gifts and generosity of our friends, but it's too tedious and complex to write out, eh? Needless to say, we didn't fully understand what was supposed to have happened until we came home and were asked about things by our friends.
We ordered a birthday gift package for my wife's mother, with a cake. We took the cake to the dining room, and gave it to the server to bring to the table after dinner. Instead of bringing the cake we paid for they brought a complimentary cake, which is essentially a section of a larger cake, and not the decorated one that my wife ordered. She was not amused.

Her Mother didn't mind the complimentary cake at all, but my wife felt as though she had paid for something (which she had) and didn't receive it (which she didn't).
Those were the "highlights."

I didn't much care for the food, I'm afraid. Not sure if this was just a one off cruise, or what but the food wasn't very tasty. We did go to the Palo brunch, but again, were not too thrilled. The food there was nicer, but nothing too spectacular. Unfortunately, I think we've been ruined by dining with Chef Josiah at Melisse.
We found the adult sections of the ship and beach to be quiet and although not always child free, mostly. We also found them boring.
Cruising with children? Definitely, absolutely cruise with
DCL.

As for us? We'll stick with Olivia.

Or at least, NCL.
