This is what the Palo Manager told us, either an outbreak, or one in the prior few cruises. ( I will tell him, he is wrong then).
Question;- Can you tell me how you know there were no reported issues on the cruises before you? Its not something they are forthcoming about? Even if you read all trip reports here, only 5% of people on a cruise come here, and of them few actually bother making a trip report. Would they know there was an outbreak?
Actually all serious outbreaks are reported to the CDC and you can go on their site and see all the outbreaks on any cruise ship.
It is my experience that they serve you on the 2 newer ships all the time but it varies on the classic ships.
