I would go for Switzerland nevertheless - even if there is no snow at
lower levels it is very easy to pop on a rack railway or cable car and
see loads of the stuff (even in summer) - besides which, the scenery
is stunning and the country, apparently, is dry-cleaned and vacuumed
every night (though the grafitti seems more difficult to remove).

Better still, go to Bergen in Norway - lovely city (which probably won't
see snow at Christmas), but the Hardangervidda mountain plateau is but a
short train ride away through some absolutely stunning scenery. Bergen
has a funicular railway and a cable car to take you into the mountains.
Even better would be to go half-way to the small but pretty town of Voss
where you'd be more likely to see snow.
