I plan to take TGV from Paris to Chamonix. I have to transfer the train at St-Gervais-Les-Bains-Le-Fayet. However,when I get off TGV at -Gervais-Les-Bains-Le-Fayet , I only have 7 minutes for catching up the last train for Chamonix on that day. Is it possible for hopping between two trains within 7 minutes? How many platforms in the St-Gervais-Les-Bains-Le-Fayet station? What direction should I go for saving time?
If I lose that train, what can I do? Are there any public transportations available from St-Gervais-Les-Bains-Le-Fayet station to Chamonix after 8:30 PM ? If I hire a taxi travel from St-Gervais-Les-Bains-Le-Fayet station to Chamonix, how much will it about cost?
