Hi Pix, I'm just back from the Travelsphere version of this hol, which includes Chile and Mendoza in Argentina as well. It goes to all the places on the JY version as well - Buenos Aires, Iguazu Falls and Rio. I'll be writing a testimonial on this hol later today as I went as a single traveller and a few folks asked if I'd do a review of it out of interest. It was a wonderful holiday, so check the Testimonials section later!
Cheers,
Bob
