Bayreuther Festspielhaus 

My dream !!! but so expensive !!!!

well, not only that ;)
You'll have to wait for years to get a ticket, and short reservations of hotel rooms are impossible during that time!

But for me as "a Bayreuther" the time before the Festspiele - as it is right now - is the worst:
building stes and closed roads everywhere in town, there's no getting forward and every one is always late (i hate being late, and i hate waiting ;) ) :(
