I'm arriving to Foz do Iguacu by plane on the Brazilian side around 2pm. I want see the falls from the Brazilian side properly before I across over to Argentina (where I'll be spending the 2 night). Is there somewhere I can safely leave my backup until I'm ready to cross over to Argentina? I plan to spend the next day on Argentinian side ...and maybe cross over to Paraguay...just to say I've been there...LOL :-P. The day after that I will have the whole morning and part of the afternoon until I take the bus to Buenos Aires. I may take the earlier buses so I can stop at the Jesuit Mission...does that sound feasible?
