Yeah, this led to a little squabble in our family. I was asked by very official-looking people, where we were going, and they would direct you to an inner path or outer path. I reaslize now they were going to direct us to that door number regardless. There they have cabs, but they are unmarked and more expensive. My mom had watched a lot of videos and was unsure. After a long flight though, it seemed legit. Like, why would the airport allow that? But, she insisted we go back to the other cab stand, and she was right. Just go to that - they have lights on top. You can probably use Uber too, but I am not sure where you pick it up.
