It was also very easy to use the AR Skyteam lounge near Gate 15 (almost right after passing through passport control). Our departure gate was Gate 9, which was only a 2 min. walk away. I seem to remember other posts complaining about how long of a walk it was to the lounge, but perhaps those posts refer to the AMEX lounge.
The AR lounge had plenty of comfortable seating and a nice selection of drinks (including Bailey's and local malbec). We chose to head all the way to the back area, which had its own snack bar and was mostly empty.
