I'm heading from Buenos Aires to Lima within the next couple of days to meet a friend. Last-minute plane tickets are a tad pricey and to be honest, I'd rather throw myself into the adventure of a 3-day bus ride anyway. But I'm suddenly hesitating because I'm getting some really mixed advice on the trip, though it may be from people who don't know what they're talking about. I'm a 20-something woman, very clearly not South American, and my Spanish is okay to good. I'm not really concerned about comfort issues -- what I want to know is whether this a notoriously dangerous bus ride (as someone told me), and whether it would just be silly for me to chance it alone. (Others have told me I got weirdly negative advice and the trip is no big deal at all.) Also, any tips would be appreciated, including bus lines you recommend or advise against, or any other tidbits you might want to share. Thanks so much.
