Hi, Cassandra!
Having done a Disney cruise that left on Super Bowl Sunday, I can tell you unreservedly that several parts of the ship are definitely dedicated to sports fans!
The huge projection television over
Goofy's Pool (Deck Nine) is tuned in to receive the game live via satellite, and the chefs prepare a special buffet featuring typical viewing fare: wings, hot dogs, nachos, and more. Additionally, several of the pubs and bars on board were offering fans other viewing options, always accompanied by delicious snacks.
With multiple viewing locations and loads of snacks, you'll have no trouble making the big game that much more - wait for it! - "super"!
Do bear in mind that Disney works diligently to resolve any possible broadcast right issues between networks and satellite providers, but that such legal arrangements can be out of Disney's control. This is not at all likely, but it is always possible, Should this happen, you will have plenty of other fun activities to occupy your time -- and you can rest assured that the crew aboard will be apprised of the score and pass that information along to their passengers.
Bon voyage!
See you later, celebrator,
-Deborah B.
