bought the train tickets paris to libourne. booked the hotel and caves. today went to make the car reservation only to find out that the europcar agency is NOT OPEN ON SUNDAY. we come in on Thursday and leave on a Sunday evening train. I don't have a lot of hair and I'm pulling out the little that is left...please help. Suggestions? I couldn't figure out if there is a different nearby Europcar station to drop it off at and catch a cab back to the station....ANY ideas. how in the world could a car company which caters to tourists and vacationers be closed on a sunday??????
