I am looking at going to Matilda soon and was wondering if anyone has done the 16-25 day seat promo before? I am looking at going on a Friday and noticed on the website that it is available at the box offices descression. Do they release them for every performance or just the less popular ones like midweek? Also I noticed that the box office is open at 10am but what time would you advice getting there? Do they sell out quickly?
