Hi the financial problems have pushed the peso down from 1peso=1 dollar to
aprox. 1 dollar=3.60 pesos, which has turned everything much much cheaper.
>From that point of view it is a tourist paradise, on the other hand the financial crisis has turned Buenos Aires's street less secure. Many tourist go all the time.... I was there early this year and everything was ok, however there is no vaccine against crime any place.
Iguazu falls is a fantastic destination. It is one of the most beautiful places to visit ....pick up a hotel in the park, like the Sheraton , there many tours that are fascinating ( and I do not like tours).
Good luck. Graziella Miami Beach
