How to charge for 2 added nights stay?

[Annie95]

I can't work out how to charge my current guest for 2 further nights stay. Theyve already paid for 2 nights via special offer, but i dont want them to pay cleaning and added fees again. Many many thanks if you are able to help.

Guest reservation => Change/Cancel => Change => adjust dates, and make sure the automatically calculated amount for you is correct or needs to be adjusted (can be overwritten).

System calculates end total for guest when you send it off. Guest must accept for it to be confirmed.
