Hi, we have a chalet booked in Serre Che for early March and have people returning to Grenoble airport on two different dates, a wednesday and a saturday. Looking at the advertised airport taxi transfer services they are mega expensive (especially for the single person returning on the wednesday). Can anyone recommend a cheaper way to get back to the airport? Unfortunately the trains from Briancon to Grenoble leave too late for their flights.
Thanks in advance.
