Can I still enter or leave during the event?
Yes, you can still enter the venue after the event has started. During the show, you can leave the concert hall (e.g., for a drink or the restroom), but you can't leave the building and come back in later — your ticket becomes invalid after a single scan.
Can I still get into the venue if the event has already started?
Yes. Doors typically open 1.5 hours before the show starts, but if you arrive later, you can still get in as long as the event is running. Keep in mind that during an already-started show, you may need to wait for a suitable moment (e.g., between songs) to find your seat, so you don't disturb other visitors.
Can I leave and re-enter the concert hall during the event?
Yes, within the building this is possible: you can leave the concert hall, for example for a drink at the bar or a restroom visit, and come back in afterward.
Note: this does not apply to the building as a whole. Your ticket becomes valid for a single scan at the entrance — if you leave the building itself, you can't re-enter with that same ticket.
