KU fan here, coming in peace. We hoped to join the Blueblood Regional next weekend, but it definitely wasn't our year. If you are coming to KC and have extra time, I hope you will check out two unique museums in KC: the World War I museum near the Crown Center area (https://www.theworldwar.org/) and the Negro League Baseball Museum (https://nlbm.com/). If you stay in one of the Crown Center hotels, please know that our awesome and free streetcar goes from 25th & Main Street right up to a block or so from the Sprint Center. The Sprint Center has one of those open air areas with huge screens that fans will gather to watch the other games or if they haven't scored tickets. Lots of bars and restaurants near there. The Country Club Plaza is the very nicest area in KC with more hotels and restaurants. Have fun!
