The inaugural cruise now departs May 20 and will sail from Venice to Athens, with a second sailing departing May 27, returning the ship to Venice.
Passengers booked on Regal's previously announced maiden voyage have been automatically booked on to the May 20 sailing. They have until November 15 to decide if they want to take the new cruise instead of, or in addition to their existing reservation.
Regal Princess is a sister to ship to Royal Princess, which debuted this year.
