I mean, it's not the only factor. But it's a factor
I'm thinking about what you mean by "without a car". That was my exact scenario. Fly in, take a 15-minute Uber to your hotel in the Jerry World complex, and walk to the game. When not at the Super Bowl, enjoy the Texas Live district, which is also right there and walkable. I'm also thinking about recent Super Bowl sites, and I'm scratching my head to understand your meaning.
