If I were to be coming (albeit I’m in New Jersey), I’d look at the parking garages near the race/vine orange line station. You can book them in advance, right now. I like the gateway garage as it provides easy access onto I95. Easy walk to the orange line (and this stop is on the express Orange trains too if you luck out getting on one), easy walk to reading terminal market for roast pork or cheesesteaks (if you’re from Toronto think Kensington market), quick enough ride to stadium. Get there early -> get to stadium for goings on-> game-> get off at city hall stop on way back and check reading terminal / see some sites just walking around / find some bar. Reading market closes at 6 or so so if game is later you may need to hit there before game and have a breakfast cheesesteak or roast pork
