G Adventures Tours are hosted in over 100 countries and run the gamut from classic and 18–30 tours to wellness, rail and local living tours that base travellers with a host family. Most of the trips do not have a single supplement and accommodation is based on a twin-share basis with another traveller of the same sex.

In 2026, several major tour operators have eliminated or significantly reduced the "single supplement" to cater to the booming solo travel market. G Adventures and Intrepid Travel are industry leaders in this regard; they do not charge a supplement if you are willing to be paired with a same-gender roommate. If a roommate isn't available, you still don't pay extra. Exodus Adventure Travels and EF Go Ahead Tours also offer dedicated "Solo Only" departures where a private room is included in the base price, effectively removing the supplement. For younger travelers (18–35), Contiki uses a similar roommate-matching system. Other luxury brands like Tauck and Abercrombie & Kent frequently run seasonal promotions where the single supplement is waived on specific river cruises or land tours. These companies recognize that solo travelers now make up over 40% of their bookings and have adjusted their pricing models to remain competitive in 2026.
