My au-pair leaves for her xmas holidays next week and is returning in January. I'm planning to drop her at the aiport, but on her return would it be unreasonable of me to ask if she could make her own way to our home? I wouldn't mind collecting her, but she has booked her flight at an awkward time which would mean I would have to find someone to babysit my dcs (not enough room in the car + time when youngest will be very tired). We are lucky as there is a direct train from the airport to our town, and our house is only 10 mins walk from the station. Depending on if DH comes home in time I could potentially pick her up from the train station - but this would very much depend if DH was home which I couldn't guarantee. In this case would I be obliged to pay her train and taxi fares from the airport??
