On trips where there is a big time gap between AEP and EZE legs, I always am tempted to find a guarderia or someplace I could leave my luggage and go out in the city for a few hours, rather than have to go right to EZE and sit around bored. I never ended up finding anything (although once I wandered the costanera with my big roller bag for a while...lol).

Is there a place at AEP where I could pay to leave my luggage for a few hours, go out into Bs.As., and then come back and get it while getting a cab to EZE?
