Hi, taking my first trip to S. America this Sept, so first time in this forum. Three adults are arriving IGU on the Brazilian side at 6:05p on 9/21, and departing also from IGU at 12:43p on 9/24. So, we have two full days there, and are planning to spend one full day each on either side of the falls.

I've read arguments about going to which side first, but more importantly, where would you stay? With a relatively late departure on 9/24, I assume we can actually spend all three nights at the same hotel in Puerto on the Argentinian side - that way we don't have to switch hotels. Is that reasonable, and are we missing anything by not staying at least one night in Foz on the Brazilian side?

Second is transportation. I have seen all the taxi costs, and wonder if it makes sense for us to rent a car at IGU instead (which I know is okay to drive to Argentina with the Carta Verde but NOT Paraguay). Will it be a hassle if we just just taxis (or even buses) and go back and forth the border during our days? I have driven in various non-English countries with no issues prior.

Thanks for all information and tips.
