Just to tell you a little about nationals...
The reason that the host team is always included is that the host organization is in charge of organizing the affair on the ground. They pay for the ice, they get the volunteers to work the event. And if the sell enough passes to see the event, they may actually make a couple of bucks. But more importantly than making a few bucks, it is the opportunity to have your kids exposed to the top teams in the country is what makes organizations sign up to host nationals.
With the change to "super-sites" (24 teams) to be implemented beginning next year, my understanding is that a single 4 sheet facility will be required to host going forward. So the "small organization" that is way out of its league at nationals won't be a common occurrance in the future. Most small organizations don't have that type of facility.
Having been to a girls nationals that ran at 2 2-sheet facilities last year (Centennial CO) and about to go to another this year in Buffalo, I really look forward to having it all in 1 building. Being able to watch that much high level hockey at 1 location going non-stop from about 8AM till about 7PM is a real treat for parents, players, and the hockey public at large.
And with the large facility in Buffalo, you have a fairly competitve girls hockey organization that while not favored to win any division, won't embarass themselves.
The only downside I see in the new format is a relative lack of willing girls division hosts with 4-sheet facilities. Perhaps some large girls organizations in Detroit will step up now and try to host for once.
Been there, done that. Went somewhere else and did it again.
