Usually you lock down your date at a venue and then send out invites, but seems a bit confusing with a destination situation. I don't want to get a big or medium size venue if not that many people show up and it looks like no one is there, but then I don't want to get a small space or be in a certain space and we have a lot of people. Did most people just decide this is what I want and that is that...did you just tell people Vegas and then send info packets later while you figured it all out? Seems like it would be easier if you just knew the amount of people...sigh
