I've attended two games at Hard Rock, and I haven't decided whether it's worse to drive or using ride-share. Like Orchard Park, there's gridlock for a few blocks around the stadium. I'd consider scouting for parking far away or walking a bit before ordering an Uber. Maybe a mile or so. Even after a 35-0 Bills win, there were still a ton of people and traffic at the end of the game.
The stadium is nice, although not nearly as great as SoFi, but it's somewhat easy to get around, there are a lot of food and drink options, and the bathroom lines are not too long. One caution: seats in the sun can get very warm, even in November. Use a hat and sunscreen, and avoid dehydration. Both games folks needed medical attention.
Addendum - I see a lot of folks warn about the sun. It's no joke and can be miserable. Go Bills.
