We will be bringing USD to Nicaragua and our Canadian-bank issued debit cards.
a) Should we exchange money at the bank or at money changers?
b) Will we be able to exchange $ in the airport?
c) We are arriving in the evening. Im assuming that places to exchange money wil be closed by then. Do some places readily accept USD so that we can get some food, drinks, cab ride once we arrive? (We'll either be heading to Granada or Leon.)
d) Are ATMs readily found in Granada and Leon? What about smaller places like Ometepe or the Corn Islands?
Thanks!
