Noon basketball should clear out before 3:30 hockey

Kind of hard for anyone to give you a definitive answer as this has never happened before. I'm guessing it's going to be a real mess around 2:00-2:30 with basketball leaving and hockey arriving.

One strategy might be to look for a spot before basketball ends assuming basketball doesn't take the western most areas of the stadium lot

Another might be to wait until about 2:30 and hope basketball is gone

Good luck - you might call ticket office for recommendations - maybe they will close off stadium lot to basketball parking. If your parking pass is for Joyce lots, I'm not sure how that will work
