It happened one time for us in 5 cruises. There was some major failure when we were at CC. I phoned the main desk after we re-boarded Fantasy after lunch on CC when I couldn't get hot water for a shower. I also called the SPA and they were out, too. It did Not take them long to fix. I kinda think I might have been the first person to report it. We were pixie dusted with chocolate strawberries in our room later that night.
