Anyone who would rather not spend their holiday working out bus timetables.
On our trips every journey between stops is a private car with a driver who knows the road, not a shared minibus you wait an hour to fill. The driver stays with you for the leg, stops where you want to stop, and knows which roadside places are worth pulling over for.
Cambodia is not a difficult country to move around, but the gap between a good journey and a bad one is mostly down to the driver and the vehicle. A shared minibus is cheap and you will survive it. A private car costs more and turns a transfer into part of the trip.
We quote every leg rather than publishing a rate card, because the price depends on the route, the vehicle and how many of you there are – and a headline figure would be wrong for most people.
