We want the concert to start on time. Therefore, we cannot guarantee access to the hall or your seat after the start. Sometimes the company has no objection, and we may still allow you to sit in a place where neither the audience nor the performers are disturbed. If you arrive late, an appropriate moment will be waited for to enter the hall so that it disturbs the cast and the audience as little as possible. When the concert has no break, it may mean that you cannot enter the hall again. At standing concerts, you can always enter and exit the hall.
