Just wanna share my experience. I just got back from Bali last week. I booked Wayan (The Wayan of Low Yat fame) and we agreed on the pricing before hand. When I got there, he contracted out the job to another driver. This driver had no clue about location of places and was very reckless in driving (almost got involved in accident 2 times).
At the end of the 1st day, he asked for 225k RP instead of the agreed 175k RP (half day rate). I got mad and called Wayan and asked him why. He claimed that my trip was far (i stopped at Batu Bulan enroute Ubud) which he was very well aware of. But since it was a difference of 50k rp, I paid him anyway.
At the end of 2nd day, I paid him RP300k as agreed for a full day. But on that night he texted me saying that the trip on the 3rd day will be RP 450k because I am going from Ubud - Kuta - Jimbaran - Ubud. I told him to screw off and logged on to a bali travel forum to search for other driver. Came across this name that was highly recommended. He asked for RP350k for the same trip and I agreed.
This driver's name was Made Chandra from Ubud. He was uber polite and quite "seng" to customise the journey after getting to know more about you. We told him we wanna avoid the touristy place (ok ok Jimbaran was the exception... the wife was askin for it... DUN GO THERE IF YOU CAN HELP IT! RIP OFF!!!) as much as possible and in the morning half session, he drove us around the balinese villages and even brought us to a temple havin some celebration with cock fighting and warung serving babi guling. This sight, I guarantee u will not see on your regular travel itinery. We had a time of our life. I'd highly recommed this guy.
His number is +6281338927502 . You can tell him Eric from malaysia recommended you. Have a great time there! quick email (balibestway@gmail.com)
Thank
