what i want to know forget the whole costume and non costume thing, if the wedding takes place in the batcave, how in the hell do the villains know where it is

I don't think the "cave" is the Batcave.  I think it's the Justice League Cave in Happy Harbor, first HQ of the Justice League (and later Young Justice).

(Besides, Bruce would never cater such an event at home ;) )

That's um..some wedding dress..

Finally. Took them long enough. ^_^ Congratulations to the two of them.
