i want to go to the final match and hoping for a overall 2 week vacation next year to brazil. i may not have a friend come with me but don't want to miss out on the experience. i am planning to go to iguazu falls, salvador, and rio. How safe is it for a 20 year old asian origin teen female during the world cup??? a lot if people during that time will be present. will it be safer and good or bad?
also, any suggestions on safe neighbourhoods and transportation options will be appreciated.
