Hello all. My first post. I agree with all the above posts relating to infectious diseases. Air conditioning is not mandatory for germs to spread, any captive audience in a confined space will suffice. I was an Engineering Officer with P&O-Orient Line between 1956 and 1963 and remember when a complete deck's accommodation was commandeered as an isolation area, packed with patients with Asian Flu when we docked at Tilbury. I forget the year but the ship was either the Orcades or Oronsay and neither ship was air conditioned at the time. Having said all this I just hope that the crew and passengers on Oriana's final cruise are all healthy as my wife and I are booked on it celebrating our diamond wedding. Looking forward to cruise for three reasons. It will be our fourth run on our favourite ship Oriana. Secondly it will be our second anniversary at sea, (our golden was on Artemis in St Petersburg) and thirdly I was on the first Oriana on its maiden voyage in December 1960 and now sailing on its final one. End of an era perhaps?
