Especially if you havent been to Bali before i would definately suggest getting a driver. The one my friends and i use is very trustworthy,reliable and friendly. His contact details are :
Made Mangku Ph From aust : 0011 62 8123931887 or
In Bali : 08123931887
Made has now both a car an the van depending on how many there are . He can also drive larger groups with the both seating around 11.
His prices are quite reasonable and definately worth it.
For a full day around 300,000rp but will also take you out just for a few hrs ie to restaurants etc. Made is also exceptionally good with kids and has two of his own.
If wanting to contact Made suggest a simple text message with planned dates prior to going and he will usually get back to you quickly. Judi
