I've been wondering the same. I have a flight from MIA-EZE Aug 21st currently. I just received an email from the hotel I was staying at, Hotel Panamericano, and they have canceled my reservation. National Decree from National Govt forbids Argentinian Residents and Non-Residents guests in a hotel until Aug. 31st. Basically, it looks like they are closing all hotels until then, at least based on what my email states.
