I have not booked my domestic flight yet from Buenos Aires to IGR airport, but from what I have researched you are better off to stay in either the Brazil side or Argentina side but no need to book a hotel in both places.
I was thinking that I would fly from Buenos Aires to IGR airport and somehow transfer over to stay in a hotel on the Brazil side, depending on what time I arrive I will spend a few hours on the brazil side and then go to the Argentina side the following day, after I have finished on the Argentina side then I would collect bags at the hotel and get a flight to Salvador for my next stop.
My question is, do you have more choices of accommodation on the Brazil or Argentina side? Also, does any of these sides have better entertainment or things to do than the other?
Also, does my plan make any sense.
