I'm from the USA and just returned from Bali. I contacted a driver through this site and set up pick up times and costs before I arrived. Worked out great. I had him drive Kuta-Ubud, Sidemen-Pemuteran, Pemuteran-Seminyak. His prices were better than the hotel quotes. He has a van with a/c and speaks good english. He works a lot on referrals. If you have questions, please feel free to contact me.
