Sectional Seating is a combination of Assigned and General Seating. Instead of tickets being assigned to a specific seat they are instead assigned to a designated section. Individuals with tickets for a specific section can then sit wherever they like within that section. With Sectional Seating ticket prices usually vary depending on the section that the ticket is for, which will be reflected in the event's price list.
Sectional Seating is available on a first come first serve basis during the performance. Show up early to queue for best seats. Like a movie theatre, individual seats are not preassigned by the box office.
