Get people out on time
Remember, the whole point of this little pre-fete was to loosen up before going out. So make sure your crew, you know, actually goes out. To prevent your event from becoming a full-blown house party, don't be shy when it comes to rounding up the troops and herding them through the door. It's up to you to make sure you don't miss your dinner reservation, or that friend of a friend's birthday bash. Plus, you won't have to worry about waking up with people passed out on your couch.
