1. Go to Properties > Edit > select property > Settings > Go.
2. Scroll down to the heading "Short breaks". Ensure your Min. and Max. days are correct and click "Update short breaks".
3. This will automatically update your short break Min. and Max. settings in your price planner.
This method saves you time. The alternative would be to go into your price planner and click to manually update each short break Min. and Max. day. This setting does it all for you in one click.
