Subject: Iguassu Falls on the Brazilian Side
Hello, I will be travelling to the brazilian side of the Iguassu falls and Ive heard so much controversy about currencies that I would like to ask those who have recently been there: is it better to take US dollars or reales? Can anyone give me just an idea of prices there? Ive been to the argentine side several times but never to the brazilian one, and any advice you can give me will be very useful.

Thank you!
