Generally happy with tour.Well planned ,covered a lot.And was running smoothly thanks to V.Posse.We would have two suggestions. 1.In Argentina,ElDorado,rannch was such a wonderful event.Why it laseted only few hours and instead driving to brazil side and do the iguazzu falls and then back next day to argentina again...when a stay in ranch would make much more sense and would save us from up and down traveling. 2.Please ask tour guides to be more informative about day ahead-here everyone was asking individually and this is tireying for both parties.Easier is tell everyone in one go..how many hours bus drive,what time is stop to eat,whats planned for evening etc.
