Argentina, Chile or Brazil
 

Hello,
I am trying to decide whether to go to Argentina, Brazil or Chile in March for approximately 12 days. I would like to spend about half of it on the beach, the rest touring. Does anyone have any thoughts?
Thanks!

I live in Brazil and have been in Argentina and Chile at least a dozen of times (in each). If you are a wine fan and your master plan were to visit wineries my suggestion would be: go to both, Argentina and Chile. But since you are planning to spend half of your trip on beaches there is no doubt you should go to Brazil.
