Festival GA: Medium
A festival layout of about 4,006 capacity: standing general-admission pens in front of the stage, with a raised VIP booth deck behind them.
Pens are capacity areas rather than seats, so the chart is about where the barriers go and how many each pen holds; the VIP deck stays individually bookable.
Try resizing a pen, adding a barrier line, then previewing how a GA ticket and a VIP booth are bought differently.
