Costs included in the price
The extra costs that you currently have set with a price of €0.00 are in the new situation automatically set as 'Included in the price'. They are no longer listed under extra costs, but are now listed under 'Included in price'. If you have more amenities included in the price, you can also add them there by clicking 'Add amenities'. Is a cost set as included in the price, but you want to charge for it? Then you can remove it by clicking on the 'x' to the right of the relevant facility and then add it to the additional costs at the bottom of the page.
If you have set costs that are no longer supported as inclusive, a notification will also appear. You should then remove these costs as inclusive. In this article, you can read what you can best do with this.
