I was on this ship. It is true that they had issues with the check-in app and YTD. it was always a long wait. It is what we expected being on a spring break cruise with that many people. And although it was sunny on the day we went to Roatan, there was extremely high winds. Carnival made an attempt to dock the ship but was unable to safety do so. Which is why i think most to TOP deck amenities were closed. As far as Noro, don't know anything about that. i would assume it would be in Carnivals best interest not to have a sick family walking around spreading germs....
