I have only been to Rio once, and that was a long time ago (2009 I think) so I can't speak to what it is like today. Back then it was good, but it wasn't cheap compared to Sao Paulo standards. But there was a lot to see and do with the beaches, cable car, statue of Christ, etc. I have been to Sao Paulo probably a dozen times in the last 10 years, most recently this past April. Sao Paulo is one of the best big cities for mongering the world. The women are beautiful and plentiful. As someone else mentioned, what would cost $350 in a major US city would cost $50-$75 in Sao Paulo. It is still good today, but it was even better back in the 2012-2017 period, I think more of the really top girls can make good money doing OnlyFans and online stuff so the quality has dropped off a bit. But it is still good. The other thing to keep in mind is that Sao Paulo is a really big city, a concrete jungle, so other than mongering and the food scene, there isn't a lot of stuff to do. There is no beach, there is no golf, there isn't much else interesting to do. Also, 95% of stuff is in Portuguese so if you don't speak the language that is another consideration. At 4/5 start hotels there are only 2/3 English TV channels.
