Also, thanks for all the information about not wearing shorts. Being that I live in California, I was planning to wear shorts and flip-flops during my entire trip, except possibly for going to clubs at night. I guess I'll have to rethink my wardrobe and packing.
Would it be acceptable to wear shorts on the plane to Iguazu, and while visiting the Falls?--I imagine it will be quite hot and humid in February.
