I booked a transfer from CDG in Paris. The good: the driver was there on time, and got me to the right place (almost, he had the street number 16 instead of 19, no big deal, just across the street). The bad: I don't know why the driver would assume I speak any French. He kept calling me as soon the plane landed. And why he would assume I have local cell service. The free wifi at CDG is spotty at best. Finally he wised up and started texting and with Google translate we found each other. Also, they wanted cash. That's my fault, in part, for the oversight, because the ATM at CDG all charge an exorbitant fee. I ended spending almost $90 for a $58 ride. Lesson learned.
