Myself and girlfriend will do a trip to Brazil the end of the year/start of next year.  We plan to have 3 - 5 days in the amazon and would like to see as much and get a feel of the rainforest as we can in that short time.

on the web there are many companies and many tours its a bit confusing so looking for advice and or recommendations of tours and companies, if any one has some great experiances or even bad ones to avoid.

thanks for any tips!
