Only singles and solo-travellers can participate.
This tour is designed for people who travel alone. In this group tour everyone is single or travels solo without their partner. Couples and families are not welcome. Sometimes these groups are even in your own age group. You can herewith discover the world with other singles.
As a solo traveller you can of course also join a regular group tour and have a great time. Many people travel in group tours: singles, couples, friends and families of all ages. Some major operators like to emphasize that 50-70% of their participants are solo travellers.
