Agree with FHEAD...best to consider a stay in someplace like Gainesville (about two hours north of Tampa) or Ocala where you might be able to score rooms that weekend in decent hotel for under $150
Super Bowl is Feb 1
Florida Gators host CBB games on Wed, Jan 28 and Tues Feb 3 so if you worked a five to seven night hotel deal one way or the other you could mix in one of those as well to further enhance the hotel being in Gainesville or Ocala.
Hotel rooms in Orlando area, west through Tampa and Pinellas County (St Pete/Clearwater) will be running literally 5x their normal rate.
I know that two years ago when the game was in Miami, Courtyard Marriott in Ft Lauderdale (90min north) was going for $500 a night compared to $109 regular rates.
