Just know that you can only change about $80 US at airport currency changers since demonitization. The Kotak bank ATMs are pretty consistent about allowing 10,000 rupee withdrawals and they usually have cash, unlike many other atms. I just returned from two weeks in India and travelled with my Schwann card. At Kotak ATMs I was able to get what I needed to travel. Change for 2,000 rupee bills, however, is a whole other level of challenge ��
