Re: Denver this year!
In Denver there is a Springhill Suites by Marriott that is about 5 min. from the stadium. Pretty nice place and the pricing is pretty good, plus the room has a small kitchen so you can put stuff in the fridge and cook in the room if you want to. It would be about a 20-30 min walk, but do able. Stayed there for one of the Denver games and it worked out well.
