For safety reasons, guests with hearing disabilities must travel with a carer. Passengers with partial hearing disabilities can travel alone, only if they request the installation of a TDD System kit in their cabin. This kit, available in limited numbers on all ships, includes light and vibrating devices, a text phone and an analogue alarm clock.
Furthermore, wireless amplifiers and indicator lights are available in the theatre and other rooms. Indicator lights are also available in the lifts.
