You can also pay for visa on arrival. The faster you get out of the plane and to immigration the less time you will wait. Expect up to an hours wait time. There are kiosks that allow for a faster check in if you are over the age of 60 or with children.
Change a small amount of money at home to Indonesian rupiah for taxi on arrival in Bali.
Do not change money at the airport- often fees are much higher.
Additionally, do not go to just any money changer on the street. We usually use Mr & Mrs Butler as their exchange rate is good and they are trustworthy.
