Very usefull info here. One specific questions for my trip in a couple of weeks. Flying from BA to IGR (Argentian side) on Saturday afternoon 26 Jan, and leaving on Monday 28 afternoon Jan from IGU (Brazilian side) to Rio de Janeiro. So, I want to sleep 2 nights at the falls
* Am I correct that it is probably the best to go directly from IGR airport - cross the border - and sleep for 2 nights in Foz do Iguazu (BRazil)? I am thinking of Hotel del Rey. What is best transport, costs?
* Planning to go early on sun 27 by bus back to Argentian side to see the falls there on my full day . End of day back to Braz side. Travel by bus seems best to me.
* On monday 28 morning see the brazilian side in morning, mid afternoon to IGU airport and fly to Rio (Carnaval, I cant wait).
Please advise, and please give me some recommendation on transport. Rob and others, your first info was already really helpfull.
