we are staying in the nusa dua area at the grand mirage hotel..and i would like to hire a driver for a day or two to take us around to some great sites..since we are traveling from the san francisco calif area i know i am going to need at least 2 days just to relax by the pool..but still want to see as much of bali as we can..we are staying in bali for 7 days.any suggestions?
