Consider visiting sport travel websites and look for the accommodation options available near the Super Bowl. However, most of the options you will get will be very expensive, and you will have to choose according to your budget.
You should always try to book a room in a hotel well ahead of the Super Bowl schedule. If you know that you will be travelling to the Super Bowl, it is best to get rooms as soon as possible. The Super Bowl venues are announced a year in advance of the game.
Search for websites specific to hotel availability for the Super Bowl. These sites may not have rooms available for the upcoming even, but can offer useful information for the next one. Hotelchatter is one such website, which you can use to get information on accommodation options.
You can also take advantage of possible cancellations by people who already have rooms booked at hotels near the Super Bowl venue. Since people reserve rooms in advance, unforeseen events can force cancellations. Some hotels offer waiting list for rooms. You should get on as many of these lists as possible.
Spreading the money around can sometimes solve your problem. Even during the Super Bowl weekend, some hotels have rooms that become available but the staff is too busy to accommodate anyone. Tipping hotel staff may get you a room, but there are no guarantees.
