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