The HarborCenter is small. Technically too small for a neutral site. If anything, you may not want four close teams... :-)
We played a tournament there a few weeks ago. It's small for sure, but at the size of the recent Final Fours it will just be big enough. Locker rooms were okay size. Ice was pretty good. There is also a side rink for practices as well. Expect $30 to park in the garage right there and the 716 is pretty $$....and dont go with a big group, they wont split checks. We like the little pizza/brewery just up the road by CanalSide! Cheaper hotel too!
