Does the NCAA get the ticket money for the WCWS? Now the quality of the facilities can be a concern, as I am sure the NCAA would like a venue that can comfortably accommodate the anticipated crowds.
So, on Saturday, UNC hosted the ACC championship game. I left after 15 minutes and went home and watched it on TV because I couldn't see. Some places in the portable bleachers wouldn't allow you to see home plate (ie, the batter). Some places in the permanent section couldn't see LF because of the portable seating. And dozens of people were standing on tip-toes and peaking in odd places, hoping to secure a good glimpse. People in good seats were afraid to go pee for fear of losing a cherished sight line.
Don't know what it's like at Minnesota or James Madison, but I can see where facility might be a concern. I do think it's fair to have certain minimum facility and ticket-sales requirements to host. Shouldn't effect a team's seeding, but I don't think it's wrong for the NCAA to hold the NCAA tournament to a high standard. Just don't pretend that Minnesota is the #17 seed. Make them the #9 and send them on the road if they don't meet the standard.
