Off-campus guest tickets can be purchased through the online store, however they must be "pre-approved" and added as an unpaid guest ticket in the corresponding 5-Star Students event.
This also means the student host must have a ticket (paid or unpaid) for the event.
To get started, navigate to the Tickets page for the event:
If the student host already has a ticket, click the expand arrow to the left of the individual's name. Then, click 'Add Guest'.
Enter the guest information and make sure to set the Amount Paid to 0.00. This will enable the guest ticket to be purchased when using the online store.
For a new student ticket, click the blue 'Ticketing' button back on the Tickets page. Look up the student by ID or name, then change the Amount Paid to 0.00 and click the Update button. Finally, add the guest information, set the Amount Paid to 0.00, and click 'Add Guest'.
Now you'll have 2 new tickets (the student and their guest) which can both be purchased online.
