Wife and I are spending two weeks in So. Amer; arriving in MVD, ferry to EZE, flying to SCL, hanging out there for a bit, then home to LAX.

What are your thoughts on getting to Iguazu Falls from either MVD or EZE? Is either one easier than the other? With roughly five days allotted for each country/city, would it be advisable to spend the time going?

I know we can't do it all, plus it can give a reason to return if we don't go now, but I think it'd be nice to see it after reading all the comments and seeing pictures.
