A quick update on chalet availability for you...
Seven berth chalets are now completely SOLD OUT.
If you're after a 2 berth chalet there are still a small amount of them spread over Wegottickets, Gigantic and Lastminute.
Finally if you want a 3 berth the very last ones are on Gigantic and Lastminute.
These amounts are very limited though so be quick if you want one.
