Arenas will not allow us to enter until 15 minutes before the game. 

Plan to arrive at the arena 45 minutes before game time.

The girls will do a 15-20 minute OUTDOOR warmup together. 

Then the girls start to get dressed for the game in or near the car. Also use this time take their pre game bathroom breaks a few at a time. This may mean you may want a different dressing plan than stripping down to a sports bra before putting on gear.

Girls enter the arena about 15 minutes before game time and finish putting on skates/helmets/rest of their gear.
