Dragoman trips are run on a shared accommodation basis, so from the first night at your joining hotel to the nights camping you will be sharing with another traveller. They will obviously pair up people that are travelling together, and if you are a single traveller you will be paired with a person of the same sex. The rooming arrangements will remain flexible as the trip goes on, and the pairings can be changed around if necessary.
In some locations, you will stay in multi-share dorm accommodation - this could involve sharing with 4-6 other travellers, including independent travellers on occasion.
They do not offer a single supplement during the booking stage, as this will be unavailable for camping with a full truck, and difficult to confirm in many hotels. However, if you would like to ‘upgrade’ to having your own room whilst on the road then this is possible if you pay the difference yourself, subject to availability. Your tour leader will assist with this as they make ongoing bookings on the road.
