Is it possible to generate a seat map larger than 35 seats wide and 25 rows deep?
No, not in Box Office Xpress Junior. The larger Box Office Xpress program, on the other hand, has no realistic limits. However, all you need to do with Box Office Xpress Junior is create additional seating sections (which is what most venues do anyway). For example, if you have a center aisle, create one section for each side of the aisle.
