How to set up occupancy-based pricing:
- Go to Accommodation > Accommodation
- Set the "Sleeps" field to, say, 4
- Check the "Discount for single occupancy" box, and enter the single occupancy discount
- Check the "Extra person charge" box, and enter the extra charge, and the number of people above which this kicks in
- That's it: your price per room will now be automatically adjusted depending how many guests there are in the booking
