Luggage storage in EZE
 

I searched couldn't find any info about luggage storage / lockers in EZE. Does anybody have any info?

I'll be in BA, and my folks will be joining mid-trip. They're planning to meet us in IGR, so it doesn't make a ton of sense for them to schlep into BA to drop off their bags and then back to AEP/EZE for a flight--best case would be a flight from EZE a couple/few hours after their ETA.

So, what are their options? Alternatively, is there a reputable luggage->hotel transfer service they could send their bags onward with? I suppose otherwise they could just pay extra for a checked bag to IGR and back, but I'd love to find them a way to avoid this.

Thanks!
