We are taking a trip in April encompassing the places mentioned in the Topic.
I know that we will need Chilean pesos and will get some from an ATM in the Santiago airport. We will need them for the supermercado, a trip to Valparairso, and then in Coquimbo.
But then what about Equador and Peru? Will we have to change USD in each country? Will they take Chilean pesos?
In Mexico we usually use USD and have had no problems.
Thanks for your help.
