No. Well you can, but it doesn't help. Online is online and not at the circus box office. But if you have a discount voucher, you can use the online code on it to book online, or bring the voucher to the box office. Beware that one discount voucher can be used for a discount price for max. 4 persons. If you want to be sure you have a seat, we advise to book online, especially for the weekend performances. If you do not want to buy tickets online, you can also purchase your tickets beforehand at the box office on a previous show day.
