Devils on the Deep Blue Sea, one of our favourite books says that the cruise line was spectacular at staying operating in its final days, When the toilets broke on Regent Sun, were most lines would have cancelled the cruise, Regency just provided several portable toilets, which were loaded onto the aft deck. Also when the air-conditioning system failed on the same ship, it was not repaired just lied about. Embarking Passengers who questioned about the heat were advised it was due to the holds in the vessel being opened during changeover day an that once the vessel was underway the vessel would cool down as the air-conditioning would kick in, of course not being true, it didn’t work, but what where they going to do, jump overboard?
