Most places will require prior permission for anything "pro". The official policies of venues is that all shooting is prohibited, but most don't care if you're just taking a photo of friends. It's when you start shooting at the DJ or performers that they'll speak up.
In general, most club-based events do not accept WMC badges as "comp" or reduced admission passes. The WMC passes are good for the WMC seminars and tech demos, if you're just a clubgoer out for a laugh, don't bother.
