Tailgaiting at the Falcons game question...

I am coming in from Houston for the Falcons game.  I usually go to the pre-game thing with the food where the players walk by.  Not sure I want to do that this time. If I promise to bring some beer can I crash someone's party?  My wife is preggo so the only thing I really need is a chair for her to sit down.  I am not feeling the autograph thing this time.
