Hi @drsax ,
in order to do that it’s sufficient to create an Option/Extra in Vik Booking “only for children”. Please be aware of the fact that children do not belong to any pricing model, only adults do. This means that any OBP (Occupancy Based Pricing) model relies on the adults only. Children can be charged depending on their age, or with a fixed cost per child, by setting up an Option/Extra Service in Vik Booking and assign it to your room-types. You can decide also to charge them with a fixed cost per night (with various prices basing on the child age), or also by setting a percentage of the average cost per adult (Adults Rate) or a percentage of the room’s rate.

For any other question, please feel free to reach us through the contact form on our website (https://vikwp.com/contact-us) so that our support team can get back to you. Thanks you.
