After reading great reports about this driver-guide I booked him two weeks ago for my first trip to Bali. I was surprised to read several other posters here who said that they would be in Bali at about the same time and had hired him. I'm worried that he says "yes" and then sends another driver in his place. Is this possible? Have other people had this experience? I would rather contact one of the other recommended drivers from Harold's list in that case. How to know?
