I got an email from the CFP ticketing office (some of you may have gotten this too), regarding CFP sponsored activities that are taking place in the downtown LA area:
The College Football Playoff National Championship weekend provides a comprehensive festival of fan-friendly events and activities. In January 2023, downtown Los Angeles will serve as the heart of Championship Campus with CFP signature events such as Media Day, Playoff Fan Central, AT&T Playoff Playlist Live!, the Extra Yard 5K, and Taste of the Championship. On game day, Allstate Championship Tailgate will be located at Lots B and C outside SoFi Stadium.
In case you are looking for tailgating options.
