Crystal’s sisters Symphony and Serenity offer an amazing combination of space, options and outstanding service, with a more comprehensive programme on board, and carefully planned itineraries including lots of overnights in port and relaxing days at sea. On the brink of a huge period of growth, a yacht and a river vessel have recently joined the fleet while another yacht, river vessels, private jets and a trio of ‘Exclusive class’ vessels will be added by 2019.
