I may be misinterpreting what you wrote, so take that as my caveat to my response.
1) The visitor locker room is not off the main lobby. It is in the rink. They no longer use the locker rooms by the bathrooms as the visiting locker room. They haven't for many years. When you walk into the main rink area, if you take an immediate right, that corner is where they built the visitor locker room. It may still be small, but it's not the travesty they used to use.
2) They built completely new women and men locker rooms for the home teams along with office space. The women's is behind the benches. The men are behind the far end of the ice.
3) They have already hosted NCAA playoff games. Many of them. I've covered most of them. The NCAA has strict rules of what a rink and area must be able to meet in order to host an NCAA playoff game (it can differ as the rounds increase). Obviously, Hobart meets them or they never would have been rewarded a home NCAA playoff game. You either meet the qualifications or you don't. There is no in between. There is no attention getting necessary.
What's ironic about this season is the championship weekend is going to be awarded to a campus site (doesn't actually have to be on campus, it has to be the regular home rink the school uses during the season) of one of the four semifinalist. Hobart may be acceptable for a home playoff game for an early round, but in no way would they ever qualify to host the championship weekend. Hobart could go into the championship weekend seeded number one, but they won't get to host.
