WICHITA — The Wichita area is hosting a big weekend coming up, with the National Baseball Congress, the Mid-America Youth Basketball boys national tournament and the Midwest Catholic Family Conference filling up about 2,250 hotel rooms each night this weekend, and that doesn’t count the normal demand from family reunions and travelers passing through. To help reduce snarls, Go Wichita, the local tourism and convention bureau, has made itself into a clearing house for local hotel rooms. Each day it tallies how many rooms are available and where, and then send that to their hotels. If customers can’t find a room at a hotel, desk clerks will know where to send them.
