Skarpi:

We had some big dinner last year - at least those who stayed till monday morning - but then we could use the big kitchen in the hostel which will not be available this year.

And yes, those who stayed at the hostel had breakfasts together as well - provided by the hostel staff ...

The program is roughly:
make music, drink beer, have fun

For food, there is a fish&chip shop, there also is a super market, a green grocer's, a bakery. If you stay in a cottage, there should be a (small) kitchen available.
