We are planning to take a party of 10 to either Alpe D'Huez or possibly
the Gande Massive in January next season and I am searching for a good
quality 5 bed apartment or chalet. Can any one suggest suitable agencies
etc. where to look. I have looked at the tourist office sites etc and
wondered if there was anything I was missing.
