I have been reading the forums and have found the information to be very useful. I have a very simple question to ask about the car and driver costs quoted here.
I assume that the costs are based on the car and not per person. For example, if the fee is Rp 10 per km and you travel 250 km the cost would be Rp 2,500 for the car, if there are 2 travellers then the cost would be split. The reason I ask is that I am traveling on my own and was told by the agent arranging the trip that it I got another traveller that the cost would be only slightly lower but not by half.
