Ask them
No idea but you can just call the PNC Arena and ask them.
Don't know about hockey practice. I went to Monster Jam
Practices are generally closed to the public.
I am sure they do just at a different time. I am not sure who you could call to find out. Sorry I wasn't more help!!. I will say this though, the staff at the arena are very nice and I am sure if you called there they could tell you:).
