Walked right off crusie ship and there was the representative .There was some inital confusion. I thought I had purchased a private tour but learned I was part of a much larger group. That is because a 2 story river boat is the primary mode of transportation. It worked out great that way. The boat had several tour hosts that provided more 1-1 services. The primary host was great with details, history and even a free pamplet of wildlife in the Amazon. They had free beer and soft drinks, snacks of local foods. Saw the Pink Dolphins as we left the dock. We even got off big boat into 6 person canoe. Paddled back into small narrow canals to watch for  wildlife.
