A former Royal butler will share etiquette tips on two Cunard sailings this month.

Grant Harold will host seminars for passengers sailing on select Queen Elizabeth and Queen Victoria voyages, sharing stories from his time as a butler for King Charles III at Highgrove House, where he worked for seven years, as well as his days at Buckingham Palace.

Harold, who now advises royal households around the world, will sail on Queen Elizabeth’s nine-night round-trip Tokyo cruise departing May 15.

Prices start from £3,519 based on two sharing a Princess Grill Suite.

Harold said: “It will be a privilege to share my unique perspective on the British monarchy and its traditions with Cunard guests, especially on ships that boast Queen Elibabeth II and the Queen Consort as their godmothers.”
