The trip, which leads in at £10,999pp, is due to depart the UK in May next year and sees guests given the opportunity to visit Rome, Delhi, Seoul, Hanoi, Sydney and New York.
Also included in Just You’s 2017-18 offerings is its 15-day America’s Music Heritage tour, available from £3,199pp.
The journey will see guests travel through Nashville, the spiritual home of country music, and visit Elvis Presley’s Graceland mansion and New Orleans – the birthplace of jazz.
Looking eastwards, guests can opt for the operator’s 10-day journey across the Baltics, taking in Lithuania, Latvia and Estonia.
The trip starts from £1,999pp on a half-board basis including all excursions, and features a visit to an underground Soviet bunker.
Elsewhere, clients can head to Morocco and explore the city of Marrakech during a five-day break, leading-in at £999pp.
Among the range of excursions offered during the Moroccan getaway is a chance to visit the Ourika Valley and take part in a Moroccan cookery class and a folklore evening, featuring music, dancing and acrobats.
Colin Wilson, sales director for Just You, said: “For the coming season, Just You will be taking its customers around the world and to every continent. Our Just You solo travellers are becoming more adventurous every year so we have added new destinations, such as the Baltic States.
“We have also grown the number of unique holidays to some of our most popular destinations such as North America, Latin America, Italy, Portugal and Greece.
“Following the popularity of our circumnavigation of the globe last season we will once again be taking our Just You customers on a round-the-world adventure.”
