Princess Cruises is one of the dominant cruise lines out of California. They have a long history of cruises to Mexico and Hawaii out of the state. Unfortunately Princess does not cruise from San Diego at this time.
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.
The Regal Princess is one of the latest Princess cruise ships. It offers cruises on the west coast.
