Princess Cruises is one of the dominant cruise lines out of California but does not currently offer cruises from San Diego. Hopefully they will return in the future.
Princess Cruises is a mid-market brand that appeals to older people looking for a relaxing, easy vacation. They have won awards for their creative itineraries. Amenities on the ships include outdoor Movies Under the Stars, live entertainment in the Piazza, the Lotus Spa, and The Sanctuary adults-only retreat.
