A published group is 4 to 8 people. That is small enough that you can hear the guide without a loudspeaker, and large enough that the minibus cost is shared.
The day, on paper and on the road
The current 5-day route is guided in Turkish. Days have a written order: border, cities, overnight. Inside a day there is room to linger at a courtyard or skip a shop stop if the group agrees.
You are not on a coach with forty seats and a flag. You are also not on a fully private driver unless you booked that. If you want the van to yourself, say so on the contact form under a private or family trip.
We send the meeting point and the first-day timing in writing. After that, the guide is the person you talk to on the road.
