In order to purchase a guest ticket, you will first need to purchase a ticket for yourself. During the ticket purchase process, select that you would like 2 tickets. Assign one of those tickets to yourself and another to your guest, specifying whether your guest attends your school or not. If you are having difficulty because you purchased your ticket in cash/check at school and are trying to purchase a guest ticket through the app, please email support@myschooldance.com and we can help you.
