Welcome to Brazil. If you have some extra time I would recommend you to visit the South Region. It's far from where you are and a bit colder. But I'm pretty sure that it will worth the trip.
Try to google "Santa Catarina" and check whether you like it.
I'm pretty sure you will have a great time in here. Just take some extra care in the big cities .
Be safe and have a good trip
