There is little to see here in São Paulo, I mean, it's like visiting Detroit, what's in it? About 95% of outsiders come here for business reasons only. The other 5% are lost. Rio is an ok place to visit, it used to be better, but it used to be worse too, you just have to know when to go, where to go, and how to go. You could check out other coast cities if you are more adventurous-like. The northeast coast is ok as well, I would recomend visiting it during the low season (march-november), or maybe during Carnaval (february, sometimes march, depends). If you like nature, fishing, and being bitten by bugs, you would like the Pantanal. There's the Foz do Iguaçu falls, in the border with Paraguay and Argentina, there's the south, which feels a little bit like a latin europe. There's the amazon forest, but I'm not sure how's it like to visit...

Cool I'm an ambassador? Do I have diplomatic imunity?
