I don't really see this "tailgating ban" as such a big deal. It's not like a "normal" regular-season game for the Dolphins, with "normal" (?) regular-season fans...it would be kind of difficult to tailgate with all the corporate jets if they tried to do that in the stadium parking lots...
Hell - I'd fly down just to watch the corporate jets land in the parking lot!!
I said this on another thread specifically about the tailgating ... I've only been to one Super Bowl, XXI in Pasadena. Even though I flew across the country by myself, I found the tailgating before the game to be as much fun as the game itself. And because I had a seat in the top row in the Rose Bowl I could see that the tailgating continued during the game. My guess is that there were about 20,000 people partying outside the stadium while the game was going on. I was sorry I didn't get there sooner, and that I had to leave for my return flight as soon s the game was over.

I had heard the tailgating ban was at the behest of Homeland Security, not the NFL.
