I have not been to this port, which is a small native village on the Amazon, but I love Brazil. I have been there both on cruises and on my own. Not everywhere in Brazil has the crime you will find in the huge cities like Rio or Sao Paulo. Brazilians are for the most part friendly, and like Americans. Don't let others here discourage you from getting to know Brazil. I will go back in a moment if I have a chance.
Thank you for your practical words. We are going to Rio for a day and half prior to the cruise. Have made contact with a wonderful person there and anticipate that we will have a great time. Crime does exist everyplace. Any traveler that is sensible and cautious normally does not have problems.
