I take it you are travelling independently? We went to Peru back in 2008 and it was a great holiday, but it was an organised tour. I must admit I would have hesitated to go on our own, and certainly would not consider it now.
I think I should have mentioned up thread, we booked through Kuoni so although it was just the two of us and not a group, they tailored it to our specifications, I did want to include Chile and Peru, but that would have been too expensive. We were met at airports and our tours were escorted. There were certain areas we were told not to go to certain areas on our own in both Buenos Aires and more particularly in Rio.
I just loved the whole experience, some of my greatest travel memories.
