Hi @Niel3.
Whether the guest has two persons listed or not, the charge for two doesn’t appear at your end, or on the details visible for your Airbnb.
Let the guest know that to correct the information from your end and Airbnb UK, that you are required under the terms of service, to make sure the information is correct for both parties.
Send him a change of number of guest’s reservation from one person to two people? He cannot argue with this..........
Whether you choose to add the second person’s fee or not is your business, but it is your entitlement. If you choose not to, you still must have the accurate number of guests on your booking.
If you do not want to cause waves, if the amount automatically increases, you can send a special offer, or after they leave a refund for the difference. BUT get the second guest onto your books in case they cause problems!
