I'll be in Rio during the WC and would like to squeeze in as much cities as I can during my 18 day stay. One of the things I want to do is go see Iguaza Falls because I heard it's a must see for anyone traveling in Brazil. I was wondering what's the best and least expensive means to travel from Rio to iguaza Falls? Any cool cities around iguaza falls to hang out for a day or two?
Thanks in advance.
