Unlike the NCAA home courts, assigned by merit, the WNIT are actual financial bids. Arizona went "all in" the year we won and we hosted all the rounds. According to the paper Arizona got over the hump not only by exceeding the required financial bid, but by agreeing to throw a percentage of the concessions in.
I don't know if the WNIT organization makes money or not. They do get large crowds, typically, for the last 2 rounds at least, and there are minimum bids to host each round. I suspect some of the schools, with crowds well under 1000, do not make money on earlier rounds. Although they seem better this year, often referees were, well, not the top of the line, probably because they didn't pay much.
Wyoming has almost always hosted, they get a good crowd for it, they were one of the programs we outbid in 2019. They were not happy, in fact according to the paper they were completely shocked. As I say, Adia got the Arizona AD to really push it. SDS is another good crowd site. UCLA - not so much?
