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 is a vessel of imagination and opulence.  Peach and rose hand cut Carrara marble, walls finished in the finest woods and decks named after famous impressionist painters. There is a glass atrium three decks high, and a dome that opens up to a 360 degree view of the sky -- day or night.  Fountains stream into pools that are at the same time, exquisite skylights for the public rooms below.  On the Costa Allegra cruise, art and artistry round out every corner.
