Well done H and GG for stepping up and volunteering. You've clearly put a lot of time and effort into the planning already. The place and all the bits sound great!
My little point though, and it only affects a few of us, is that the DATE of the AR is as important to me as the location and venue. I can't book any time I like off work unfortunately.
I agree that a date for people to express and interest and a follow up deadline to post up fairly fully formed plans, is pretty essential.
But from experience I do think the motto for any AR organiser is
'You can't please all the people, all the time'
