Reserved seat

 For some concerts you also have the option of reserving an unnumbered seat (unallocated seat). On the night of the concert, you present yourself upstairs in the tribune where - with your seat ticket - you can choose a seat from those available.  
You reach the tribune with seats by entering the ground floor of the hall and taking the stairs near the rear of the room to the first floor. On the balcony, you then turn left to approach the tribune. There are additional ways to access the tribune, via the entrance door next to the Foyer door (on the left at the front of the hall) and via the stairs at the back of the entrance hall (Agora). Until the concert commences, there is supervision provided by the stewards on the tribune.

In the event that, for organisational reasons, a decision is made to reduce the capacity of the hall and close the tribune then the right to a seat is also lapses. Your ticket then automatically becomes a standing ticket. Reimbursement is only possible in the event that the concert is cancelled or postponed.

The possession of a reserved seat gives you the opportunity to enjoy something tasty to eat in the AB Resto, in a relaxed manner and without watching the clock. More info and reservations.
