I'm worried that this would end up being one of those situations where everyone has a different idea of where to meet, and a different idea of how many people will show up, and it will come to nothing. How about posting up a poll to gauge the numbers. Based on the numbers, pick a place and a date and stick with it. Typically what happens is if 100 people want to attend, the place and date ends up excluding quite a few. The important thing is laying down the law and if you can't make everyone happy, so be it.
