So.
The reservation system is theirs, not from PZS.
In the so-called private room, I would pay almost 50.00€ more per day just for accommodation than I paid for a hotel on the Adriatic (room, self-service breakfast, self-service dinner and drinks with dinner).
And also.
PZS pays for its reservation system, at the mentioned huts they do their own system. I think that the PZS leadership, if it felt any responsibility towards the membership, should resign immediately.
