Has anyone attended this event in recent years? It looks very interesting. Is it especially crowded at that time? Is one night's viewing enough?
Yes and the festival is amazing. Since so many locations I would do two nights and yes some locations could be crowded.
Agree to Mignon. Photo geeks spend two nights. Check and reserve early a bus tour.
I was there for it in 2019. It was great. Very worthwhile. I just did one night, but I also just hung around on Unter den Linden. There are many other sites around town.
Thank you all for the info!
