The play of light on glass and water transforms this magnificent ship into a floating work of art. Carrying only 800 passengers, the intimate Costa Allegra cruise ship is a vessel of imagination and opulence. Peach and rose hand cut marble, walls finished in the finest woods and decks named after famous impressionist painters. There is an atrium three decks high, and a dome that opens up to a 360 degree view of the sky - day or night.
