The section presents an example of a family pass package which utilizes the fields on the Web tab of the main pass item in the package to auto-sell additional pass items and to create a Web Rule to evaluate the ages of the guests attached to the passes in the package. The package demonstrated in this example consists of up to four total passes, one main pass item (family pass package) and up to three additional pass items (pass package additions) and is configured such that only two guests ages eighteen or over can be attached to the passes in the package.
