Of the hotels listed, the Marquette is more central to nightlife and restaurants.
Are you a tailgater? The lot will get going just before 7 -- regardless of temperature I am proud to say. In fact, I think the colder weather brings out more tailgaters than nice weather because all the old fans from the Met Stadium era love showing off how unafraid of the cold they are.
One of the most packed I have seen the main gen admission tailgate lot was for the Eagles playoff game at the dome at the end of the 2008 season. It was about 25 below zero. It was January tho, and even if it's possible, it's more likely to be somewhere in the teens to 20s. Just bring some layers and find some local fans who have a heat source. Grill, mainly.
Otherwise along the Vikings Plaza they have tents to take in pregame festivities. Not really my cup of tea., But maybe brunch at Ike's, then head over for a walk through the tailgate lot to see the real festivities.
The lot is along Portland avenue between 3rd and 4th
