10:00am  Princess Cruises' Caribbean Princess docked early
Friday in Houston, ending passengers' vacations a day early amid
an outbreak of norovirus.  Princess Cruises spokeswoman Julie
Benson says the early docking came because of forecasts
predicting heavy fog in Houston, not because of the illness.
But, she said a total of 162 people reported the illness during
the voyage, and lab tests confirmed that it was norovirus.  It's
the second outbreak of gastrointestinal illness on a cruise ship
this week. Royal Caribbean's Explorer of the Seas docked in New
Jersey on Wednesday, two days earlier than expected. Nearly 700
crew and passengers fell ill on that ship, the highest number of
sick people reported on any cruise ship in two decades,
according to the Centers for Disease Control and Prevention.
