Anecdotally, I hear much more German at French resorts than vice versa. Also, see the hundreds of TRs on Alpinforum to show that German-speakers love to ski in France. Many of the obscure French areas I've skied were due to those reports/I would've never heard of them otherwise.Most Germans/Swiss at St. Anton/Arlberg had never skied in the French Alps.
If we stay away from France completely (Switzerland,Italy,Austria larger resorts) do you think we will have an issue? Seems based off reading this thread the French seem to stick in France.
