I'm planning a trip to South America and am wondering which option would be better: booking everything through an agency/company or taking care of every detail myself. Macchu Picchu is our main destination but we'd like to incorporate other countries (Brazil, Argentina, Galapagos, etc) in there too, if possible.
Which is more cost efficient? Is it a major headache to take care of everything myself?
Any advice would be much appreciated. Thanks!
