Fanmail.biz

hello, I want to write to the Backstreet Boys vv but I don't know which venue to use. In the special topic for that I didn't found most of these venues. Did someone had a success from any of those venues or know that they pass on fan mail?
Thank you in advance

Oberhausen, König-Pilsener-Arena
München, Zenith, die Kulturhalle
Frankfurt, Jahrhunderthalle
Berlin, O2 World
Bamberg, Jako Arena
