Additional rate does not show on booking page
The system can handle multiple rates. A price will be automatically applied if the booking fulfils the condition.
If you want to display this as an extra price row go to SETTINGS -> PROPERTIES -> OFFERS -> OFFER 2 and set "OFFER 2" to "Show": "always. Click on edit and type in your rate name.
Go to RATES and open the rate. Set OFFER to 2- this will apply the price to your offer 2. When you go to your booking page you will now see two price rows.
