The no quarentine has been confirmed - so thats one step in the right direction. The testing after you leave the airport issue is indeed a hassle, but its being reported here that this requirement may be lifted sometime in November once the full vaccination metrics of Argentina improve beyond 50%. One other thing Im trying to figure out is if the local testing sites that are free will also be offering free tests to Tourists.... Im working on getting a confirmation of this and will report back when/if I can get more details.

I want to be cautious about this... would not want to raise false expectations.

Will come back as I know more.
