The rising popularity of solo travel is making some serious waves, with a number of cruise lines removing single supplements and creating cruises exclusively for solo travellers.

At the forefront of the movement are river cruise lines like Evergreen Cruises and Riviera Travel, a relative newcomer to the Australian market with fares up to 50 percent lower than other companies.

Evergreen is offering members of its new Evergreen Solo Explorer Club an additional $100 discount per person off their next booking, as well as no single surcharges on a range of cruises in Europe, the Mekong, Canada and Tasmania.

Riviera Travel (pictured below) has gone a step further and added eight solo-only European river cruises to its 2019 program -- five more than the three offered this year. These cruises, with all cabins sold only to solo travellers, include voyages along the Rhine, Danube, Douro, Rhone and Saone.

“We know solo travellers enjoy our river cruises and to meet growing demand, we have upped the number of cruise itineraries exclusively for solo travellers,” international sales manager Thomas Morgan said.

Fares start at AU$2,769 for a solo passenger in their own cabin -- no sharing. Bookings can be made through travel agents or on the company's new Australian website.

Great deals for solo cruisers are also to be found at sea, with ocean cruise lines getting in on the action. Until December 31, luxury cruise line Seabourn has reduced its solo supplement to 25 percent above current fares on selected voyages in certain suite categories. Normally, the fare is between 175 percent and 200 percent of the per-person double-occupancy fare.

“Sophisticated solo travellers find the ease of an ultra-luxury Seabourn cruise, combined with the care and consideration given to them on our intimate ships, is the perfect way to travel and see the world,” a spokesperson said. “That is why we always offer preferential single supplement fares on all of our ships.”

Fiji-based Blue Lagoon Cruises is also jumping on the trend, offering Super Single fares with no single supplement and a complimentary upgrade for bookings made until January 31. The offer is valid for travel between December 14, 2018 and March 31, 2019 and then between November 1, 2019 and March 31, 2020.

For those looking further afield, Adventure Canada is cutting the single supplement on its ‘In the Wake of the Vikings’ voyage from Iceland to Greenland, departing July 13, 2019 for bookings made by January 19, 2019.
