BILLY IDOL and DURAN DURAN accoustic live at Now and Zen fest

I'm from Paris, France but I'm actually spending some holidays in San Francisco and I'm going to the Now and Zen fest. tomorrow, as I'm a fan of both D.D. and Billy Idol. Yes, it's true !
My question is :
Does somebody heard about a special party for this occasion, or a place where the bands might hang out ?
I wanna have fun and make this holidays unforgettable : )

Thanks babies
