Ok, so, I'm going to be in Argentina August to December this year. All I see online is that it's free to visit for up to 90 days. Someone said in one of the threads that they don't check for return tickets upon entry, so should I go ahead and buy the 2 way ticket with my intended dates....or should i be safe and buy it for a return 90 days later and exchange that one later....are there any fees I am looking at (besides that of exchanging the ticket)? What is the cheapest/best/safest way to go about this? Any information would be helpful!
