Make your way to the 3rd floor to grab a drink and find someone you haven't spoken to yet. It doesn't have to be a big moment. A simple "I don't think we've met" is all it takes. While you're at it, pull up the conference app and connect so you leave with more than just a full stomach.
Need a starting point?
"Where are you coming from — and what does your role look like day to day?"
"What's been the most useful thing you've taken away from this conference?"
"Is there anyone here you think I should connect with?"
