Does anyone know if buses run to Aix from the airport on Christmas and if they do- what is the town like that evening are things open?
If you mean Marseille Provence Airport, I would assume that shuttle buses run whenever there are flights. However, their website is down at the moment. It's worth checking for details when it's up again:
Don't expect much, if anything, to be open on Christmas Day evening; any restaurants open are likely to be fully booked well beforehand.
