My wife sailed on the Brittanis in 1989 with her family and friends. Because the ship had been used during the war, it was quite old and spartan. Their programs were far below today's standards - especially their entertainment which was only one show per evening. My wife had the late seating and always missed the entertainment, as it was ending by the time they all got to the theater.
However, she said that the price was very reasonable for a five day cruise from Miami to Cozumel and back.
