We are planning to visit Argentina after Christmas this year. Our last stop was to be Iguazu Falls and we are trying to decide if it is worth visiting the Brazilian side. If we cross to Brazil, we could then fly home via Sao Paulo or Rio. If we do either, does it make sense to spend a day in either city? Is a day enough time to enjoy the city or would it just be rushed and a bit crazy?

So... what would you do?

BTW, I need to decide NOW to book our return tickets with frequent flyer miles.
