I'm doing it in 4 days, I've seen posts with 3 1/2 days. The prob with not doing it faster is the flights of the carriers needed are sometimes 1 per day and it leaves just as you land. Thats why I got to be in LIM for almost 24 hrs, get back from CUZ at 9am yet the carrier I need flys out at ONLY 6am.Then theres the 5 to 6 hrs layover in the airports for the same reason. On the other hand if you dont care what it will cost you you'd probably be able to cut a day off since you'll take flights that you dont need,to cities you have been to so that you can catch the carrier you need. I figured a Sun to Thur is not bad and hope I can put up with most of the down time.
