[Tagging] How to tag a social vacation centre?

[António Madeira]

Hi there.

How should I tag an area dedicated to vacations, which is not a resort,
only for members of an institution? Those centres are very common near
the sea, and they range from kids camps (sons of government workers), to
bank or police pensioners/workers.
I was about to tag that as amenity=social_facility but I can't find any
suitable subtag that conveys the idea of vacations.
