The line will deploy four ships on grand voyage itineraries, calling at 194 ports across five continents.

Andrea DeMarco, president of Regent Seven Seas Cruises, said the new voyages were targeted at more “discerning” travellers.

“These five new voyages appeal to those who desire longer, more immersive experiences, with itineraries ranging from 61 to 117 nights,” said DeMarco.

Prices lead in from just over £34,000, with the most expensive itinerary clocking in at £74,069.

Grand voyages offer guests the choice of five different journeys. The 61-night Grand Asia Exploration, for example, begins in New Zealand and Australia before heading to Bali and on to Japan.

The cruise includes overnight stays in Melbourne, Bangkok, Ho Chi Minh City, Shanghai and Osaka, giving guests the opportunity to experience the local atmosphere.

Besides balcony and ensuite accommodation options, cruise packages also include business-class flights, a pre-cruise hotel and dinner, an exclusive shoreside experience, and door-to-door luggage service.
