No, but if the highway is suffering from a lot of tacos at least there's another way around. That said, without tacos it is about 30 minutes from my place in San Telmo to EZE. It took me about that long on a nasty evening from AEP to San Telmo. Further, the night taxi fare made the ride not much of a savings from the fixed EZE fare.

I really get the appeal of AEP. Especially for those on the SEOT* For me, depending on the time of day, it really isn't worth the trouble (especially if it involves another connection).
