ESPN Club on Disney’s Boardwalk always has the games on, and will be a very popular viewing location. It has over 236 televisions, including TVs in the bathrooms and at the booth tables. If you go that route, you’ll want to get there early because they won’t kick people out of the restaurant, so your chances of getting a table during the game decrease as the restaurant fills.
I think in the past, Disney has made viewing locations around the property, but they’re announced closer to the Super Bowl. Keep an eye on AllEars.Net closer to the Superbowl.
