We would like to plan a trip to Argentina to see Iguazu Falls and Mendoza this fall. Wondering if anyone could recommend a company/person they have worked with in South America.
thank you.

I suggest you use the Trip Advisor Argentina forum´s search feature to reseach ¨Isabel¨ and draw your own conclusions. Have a great time in my country.

Are you sure you need a TA? I spent two months in SA in 2012, including Iguazu but not Mendoza. After failing to find a TA I wanted to work with (admittedly I didn't look TOO hard) I planned the whole thing myself. Pick up some guidebooks, and posters here who travel independently will be happy to help.

Hi, so this November I traveled in Argentina, and visited Buenos Aires, Iguazu and Mendoza (including lots of wine tasting of course!). I really wanted to speak and book with a local company from advance, so I found a few websites that help with that. After looking also on trip.me and zicasso.com, I finally booked with Ollami.com and was really satisfied. They helped me combin two trips they have, one to the Iguazu and one to Buenos Aires and Mendoza. Really recommend to check these sites, but if you want, this is what I based my trip on: https://ollami.com/tour/4017/mendoza-buenos-aires
