For me, it was a wonderful experience. I went in a group; they were photography trips, organized by another photographer. We visited several cities, traveling in a bus exclusively for us. We also did walking tours of the cities, but always in a group and with a local guide who accompanied us the whole time.
What I struggled with was the food, which I found very spicy. They told us that's what happens to Argentinians because we're not used to eating so much spice. When they found out we were Argentinian, they kept saying "Messi, Messi!" I don't know anything about soccer, but Messi is known all over the world!
Overall, it was a very enjoyable trip; I felt like I was in a movie because it's a very different culture from our own.
