At this point CollegeWeekends.com is a better concept than a service. The idea is that you can rent apartments or houses near college campuses for a single game weekend. Often times it would be cheaper than hotel rooms for bigger groups and usually more roomy. They have the service set up for 17 different schools but not a ton of listings yet. The first school to be listed was the University of Virginia in Charlottesville. It seems like this rental setup will thrive at schools in small towns where there might only be a limited number of hotels within miles of campus. You can check out their FAQ for the particulars.
