You can use different price structures in a package.
Package total price per person
You create a package with a price per person. Select 'included' (see image below) when products are covered in this price. These included products are displayed in the package as € 0,-.
Several "mandatory products"
You create a package and add products. Deselect 'included?'. All such products are charged by default.
Package x room rental
The correct room rental price is calculated based on the selected location and package. Go to setup > locations.
These are extra options for the client that are selected in a package (presented as photo tiles in the request module).
