Went to Tignes last summer. It was awful. We left after 2 days and went to Morzine.
Very little open (including the main lift, even though it was the ‘opening of the bike park weekend’) There was too much snow and melt-water. We could find about 1 bar open, 1 restaurant. Tiny supermarket with barely anything fresh. One outdoor shop that had a few bike parts on sale.
The Porte Du Soleil had loads of new tracks since I was last there in 2006, so it’s worth a re-visit if you haven’t been for a while.
I would plump for Chatel. Or Morgins, but I think that will cost a bit more as it’s Swiss.
