Unless there's a typo, the Big 12 Soccer Tournament http://big12sports.collegesports.com/championships/big12-soccer-championship.html will be spread out to games on Wednesday, with Thursday off, games on Friday, Saturday off (with time for local youth workshops), and the Sunday championship game, instead of playing on Thursday and Friday with the championship game on Sunday like the past few years.

Will this make it harder for our usual fans to get to San Antonio or will they just skip class for all three days?

I will proably go to at lest one of the games. I thought I would be out of town that week but I go out the weekend after that according to that schedule.
