My wife and I will be flying to Ushuaia in two weeks from Brazil. We get to Ezeiza at approximately 1am, and giving maybe 1 hour to clear customs and retrieving luggage, we will be ready at approximately 2am. Flight to Ushuaia leaves from Aeroparque at 5am. My question is: what's the best option, wait in EZE till like 3:30am or go straight to Aeroparque as soon as we clear customs? I'm not sure if Aeroparque stays open all night, hence my doubt.

We'd appreciate any help on this.

Thanks

I think Aeroparque does indeed close for a few hours but I would suggest not waiting at EZE (there is not too much to do). If you get a taxi at the airport (right outside the glass wall there is an official EZE Airport taxi service that will take you to Aeroparque for about US$14. If you have a bit of time and not too much luggage to tote around Aeroparque is in an area that is close to several nice bars and restaurants that will be open. Unlike the 2AM closing time in the US, most bars and restaurants are open at least until 4AM with some waiting for the sun to rise to see the departure of their guests.
