That is their home arena now. They have a rink on campus but have only played exhibitions there for a couple years. I can't imagine them trying to host a Hockey East game at Freitas.
I just googled it and it doesn't look horrible to me. I don't think it's a lot smaller than Merrimack or Providence's rinks. I wouldn't be surprised if Maine plays there Thursday before Fenway.
This is a little off topic, but I think the way forward is to have smaller rinks and fill them up. It's a bad look to have rinks half to two thirds full and you don't have the atmosphere with all the empty seats either. This is a problem that isn't exclusive to Maine, seems attendance has dropped for a lot of schools the last five to 10 years.
