Worked there during the last Philly Superbowl run and in Philly for 2+ years. Like others are saying go up the night before just in case. Take the train to the stadium they have direct ones from city center, don't Uber. The NFL cracked down on fan altercations so the only ones causing problems are drunk teens. Was there for the majority of the tailgating and games. Only real problems were Dallas games, just drunk teens fighting other drunk teens. Some was even eagles on eagles.

Down town the night before run around Walnut or south street a little. Moriarty's is always a fun place.
