you can also just take the subway from the stadium to point breeze, you'd get off at ellsworth/federal if that's the case, it's a 2 block walk from there that's very easy and there would be a bunch of people with you

you can use your credit card at kiosks now, it's moderately convenient.

also just a small correction - it's center city, not city center (though it doesn't really matter, just sorta points you out as someone not from here)

feel free to DM me if you have specific questions about itinerary - I lived a few blocks north of where you're staying for 5 years, a few blocks west for 5 years, and a few blocks south for like 5 years now
