Sorry for being OT but I need some help planning a trip to South America. I'll be flying BA to get there and back, just to keep it slightly on-topic.

Flying to EZE on the 15th of April. Returning from GIG on the 2nd of May.

The only requirement is to visit the Iguazu falls for a day. All the rest is pretty much unplanned. I don't mind driving. I also don't mind flying.

So, if anyone has suggestions and knows a bit of Argentina, Brazil and perhaps Uruguai, I'd like to hear from you. Hiddy, are you there?
