Well, you know girls. They like to do things in groups. They will probably herd toward a friend once they get there. See if you can have 1 girl go up to 2 and start talking.

Another idea is to do a group activity. That way when everyone is interacting all at once, it doesn't seem like they outnumber you.

I know you guys are worried about how much your chapter can handle, but if most of those girls are just totally super, see if you can give them bids. Obviously it's quality over quantity, but make sure you don't cut a quality girl because she's not the Top 10. You might not ever get her back.
