South America is a wonderful idea as far as the exchange rate. You will certainly find great bargains. Keep in mind, though, that it will be winter in July. That said, I would suggest Buenos Aires. Great cosmopolitan city, great architecture, culture, people, folklore and a city that offers many day trips or longer to interesting places.

Lidia in Los Angeles but always dream traveling...
