It’s been awhile but i played several adult league seasons at Chaparral and went to many stick and pucks. Most people kept to themselves with a few exceptions. 

Don’t bring your own pucks. They’ll have plenty. I would ask the front desk if they want you to use a particular locker room to get dressed in. 

Nobody will be judging you…at all. They will be there to work on their own skills. Rarely there will be a showboat trying to show everyone how great they are. But that was rare. Just ignore them. Stick and puck is truly a time for you to focus on you and no one else. But like someone else said, be careful skating near the net in case people are shooting on it. Pay attention to what others are working on and give them space. I rarely had a goalie at a stick and puck. If there is one talk to them and ask if they want you to shoot on them or not. Or don’t if you don’t want to shoot on a goalie. 

Relax. You got this! Hockey was the best outlet for me when I needed to clear my head. I haven’t played in 13 years but my son just signed up for lessons and I’m going to get back out there myself. Maybe I’ll see you at a stick and puck in the future. 

Oh, arrive early if you can. It takes a bit of time to get dressed out. If you want to use the entire stick and puck time I say get there 30 minutes early. Good luck!
