I was there during the Pro Bowl last year. There was no impact on crowds although I did hear that there were some players who visited the parks before and after the game.
We will be at Disney for the Super Bowl in February and while I won’t be watching, my husband and brother-in-law will definitely be. On this last trip, I stopped by ESPN Club to ask about the Super Bowl package. It is $100 per person to get a table. That $100 is then applied to you food/drink bill. However, you don’t get any $ back if you don’t spend it all.
ETA: I’m sure it will be playing at Splittsville at Disney Springs as they show the regular season games. I’m sure it will also be on in the various hotel lounges.
