I booked award tickets for my wife and I to go to LIM and EZE. Here's where I'm running into a problem. I expected to spend a day or 2 in LIM, then book award tickets to Cuzco. LAN doesn't have award tix available using my BA Avios points when I need to go. I expected to stay 3 days in EZE, then book award tix to the Falls using said points. LAN has no availability on the dates I want to go. I don't want to pay for airfare to those places, and don't want to pay a tour operator to get me there. I'm looking for suggestions on day trips out of LIM and EZE.
