Would anybody turn up if I organised a gathering for all open house fun?
I am sure some would but may well be safer to have invite only as this i presume would be in your home. This would then ensure at least a good mix of male female party goers. Posting a date and area would help as well, plus details as to if they are invited to stay over or to leave at a certain time. Are you near public transport links ? Is there good parking ? Are there Hotels near ? all that sort of info would help people to make the choices to ask for an invite. You would certainly have more idea as to who to expect and not be sitting there in hope. Saying all that you always get the few who cant come at the last min. Good Luck xx
