So you are going to school full time, dorming, and playing juniors at the same time? Out of curiosity what team will you be playing for and are you looking to play college hockey or just have fun?
As for getting to and from your arena, communicate with your coach now. He will help you make arrangements through a teammate that you likely have not met yet. It is unlikely that a teammate goes to school with you however one of them probably will have a billet near campus or past campus so that you are on the way.
On top of that good luck managing practice, gym, and your studies.
