We had wonderful service from our (newly promoted) butler on the Quest this past August. He remembered us from his days as a server 🙂
There were times I needed to request something be brought to our suite but it didn't bother me, always came. The ships are still short staffed. There were only I believe three butlers on the ship, and I know there were some demanding guests on our second cruise for sure.
When there was a serious issue, like someone writing down the wrong stateroom number on their laundry slip and we got charged for it, he took care of it within an hour. Brought us coffee every morning, even disembarkation morning.
I hope they don't change
