I am considering a trip to Peru. There I will visit Cuzco, Iquitos, and of course Lima. I expect to spend 12-14 days there. I am also strongly considering extending my trip up to 20 days or so and visiting Brazil, at least Rio, but possibly also São Paulo and maybe somewhere on the Amazon (not sure where yet). I'm travelling from western Canada.
1) Would it be a good idea from a timeline point of view? Or will it be too rushed?
2) I did some preliminary research regarding airfare, and it looks like almost all flights from Peru to Brazil will have to be from Lima (more time wasted travelling back and forth), and also one way tickets are extremely overpriced, sometimes even double the price of return tickets. Is it possible to obtain better prices for travel from Peru to Brazil?
3) How does the "amazon experience" in Peru compare to in Brazil? Is one "better"? Are they simply different and will I regret being so close to Brazil but not going there?
