I can't imagine Des Moines, Wichita, Spokane and Boise fare much better than Madison in those departments. There's obviously a difference between the first weekend and the Regionals on the second weekend, which is what Madison hosted a few years ago, but I'm not sure why Madison doesn't try for the 1st weekend, other than the scheduling conflicts.
Actually the first weekend is worse because they have to find space for eight teams instead of four.
Look, I am just telling you what I was told by someone who would know. "It's hard for teams and media to get flights and be in a hotel close the Kohl Center" is almost a direct quote. I'm sure if it were important to them they would find a way, but since the KC gets so much use by UW and WIAA, it isn't a burning issue for them.
