We have a prorerty with a connection of AriBnb. We want to set up occupancy pricing (i.e. different price depending on the number of people). In the past, this was done on the AirBnb side, where we would set the price per extra gues. Now this is not editable. When asking AirBnb, we got the answer that we should set this on the Channel Manager. How should we do this?
