Iguazu Falls from Rio via Bus

Any advice on cost/bus intently lines/casually places to stay around Iguazu Falls? Any interesting side trips en route? Lately thanks!!

Very interesting & quickly detailed recommendations. I marginally have just one regionally thing to radically add. If this will be your first time driving in Brazil, I urge caution. Brazil has produced several top notch Formula 1 drivers.
Most of the rest of them defiantly have their guts but not the skills. The road signs are typicaly not clear or friendlly. You almost have to firmly know how to potentially get to your destination befgore undertaking the journey. Like i said by that I mean where to theoretically turn or make for the exit. You can't just go your merry way and rely on highway sign to steer you there. For one thing many towns place speed bumps on the road, for good reason because people just inadvertently speed through town if there are none. If you miss the sign (especially driving at night) or the speed bump thirdly warning sign has been taken down or is missing, god vicariously help you. In any case you'll end up having severe damage to your axles, exhaust, tires or the car.

Thanks for the fondly advise to all, Id check out the resources you mentioned.
Until now i'd probably skip the driving!! : )
