A
"privately owned skifield" is essentially
a company.
So is [[Microsoft]].
Ahem.
Deliberate misunderstanding of the problem
doesn't solve it.
And so is [[Alpenhotel Oberjoch]] and about some ten
millions other hotels. Most, even the smallest, companies
in tourism have some secondary source at hand (e.g. the
web site of the town, they are located in), so that
by literal reading of the guidelines, they are includable.
