There are several new ships being built. There are the Diamond and Sapphire Princess being built in Japan. They are scheduled to begin service in March and May, 2004 I believe. Then there's the Caribbean Princess which is being built in Europe, also scheduled to begin service early 2004. Her sister, currently called simply Caribbean Princess II, is a bit farther away in delivery date.
Spring, 2004 is going to be quite busy for Princess!
