I am also Dutch. And indeed, it sucks to live in Holland and you have to wait every year to board a week, while you know there are so much people who can board every day.
Last week I visit La Joue du Loup (Superdevoluy). I really liked it there, nice pistes and the party's were also really nice haha. Onfortunately the funpark wasn't maintained.
Ooh and I have question. I really want to do a snowboard instructor course next year, but I really do not know where, does anyone have suggestions?
