It’s vacation time in Berlin. Schulferien, or just Ferien, and you can see it. Traffic is lighter. Some restaurants and shops are closed while their owners or employees take time off. Six weeks but remember the dates change every year almost everywhere in Germany so be sure to check in whichever Bundesland you might visit. Private agents often visit festivals or summer programs and ZAV keeps a skeleton staff for cast changes and the like but auditions are unusual.
