It sounds great to think just a mere 25 miles away from where I live there is not one but three sport arenas.
One of them will be featuring the Super Bowl in less than 250 days.
and trust me the hotels are counting the days ...
I just did a cursory look at hotel prices for San Jose for the mid January weekend and the prices are still considered "normal" for some hotels.
When I move up my weekend to the one prior to the Super Bowl then prices for even a Motel 6 start to skyrocket and by sky rocket I am talking about
$300 night to be next to the airport on the first floor right next to the lightrail station.
So if you want to go to the SuperBowl you may want to check some other options and be prepared to drive from Santa Cruz or Vallejo.
