Well, I'm currently on the Grand Princess in Fiji and there has been absolutely no AC on most of the ship, including cabins, the dance floor, stores, restaurants, hallways for 2 days. To be fair I felt limited AC in the art space, but definitely not normal. I have cruised on 30 + ships. This has been the worst experience for me. This ship is sad in other ways, too. But, no AC in a hot place is dreadful.
