The category name should help you and ticket buyers know the types of seats they are—for example, main floor, balcony, mezzanine, reserved seating, VIP, etc. The reserved seating category will appear on the event page to make it easier for ticket buyers to select seats. You can create as many categories as you'd like.
Note: The reserved seating category and the ticket type name (from the create/edit ticket types page) do not have to be unique. You can use the same name if needed. For example, the category could be called main floor, and the ticket type name associated with this category could also be called main floor.
