Err a travel-inn most nights of the week... and considering the number of people that must be meeting up this way these days I should think you would find more like minded individuals behind those doors than you would at a specialist event!!!
I think club 18-30 or perhaps Headonism would be more your thing... there was a channel 5 series of programs on this subject... its repeated regularly... requires a pinch of salt... but may be of use if you can avoid the tabloid BS element
have been to euphoria, its quite good.
only downside is, blackppol is not a very lush place to go.
decide on where u want to go, THEN think of some adult activites to do there.
