keep yourelf safe.brazil is not secure at all.try to enjoy the trip but keep your eyes open.my friend was in her car stopping in the red light(trafic light) when the light changed to green the car in front of her didn`t move ,she used the horn ,then a man stepped out his car threatening her with a gun .she is brazilian she said that`s normal in brazil.since they moved here her kids they refuse to go back to brazil even for vacation.
good luck
