I'm planning to travel from Toulouse to Andorra la Vella in august or september.
I know there is a bus line operated by Novatel from Matabiu station of Toulouse. It seems to leave at 10.30 am. (Is there other companies traveling from Toulouse to Andorra?)
Can I buy the bus tickets in Toulouse, at the same day when leaving to Andorra? Or is it necessary to buy them beforehand?
