My guess is you haven’t seen any of the attendance numbers of the regionals. Bridgeport always out performs the other regions when UConn is there. Actually, they have never held a region without UConn being assigned there. That is why Fairfield U and Sacred Heart U agree to host it, they know it will sell out.
The poor regional attendance is the reason the NCAA will go to just 2 sites next year, hoping to get more fans. To me, it is always about location. Put in NC or SC and those fans will come. Heck put it in Iowa, those fans attend. Don’t put it in Dallas or OKC or Lexington. Chicago is usually pretty good. Oregon is ok but avoid anywhere in California (too much other stuff to do).
