I will be responding to prompt number one.

Honestly, a locker room is a locker room is a locker room - Gertrude Stein TM.  If you’ve seen one, then you’ve them all.  Obviously, our locker room cannot be a complete nightmare.  What do I mean by complete nightmare?  Well, it can’t be:  too small, too smelly, filled with mold, occupied by weird rink squatters, occupied by weird refs, etc.  As far as amenities go, however, it is best to keep it simple.  Ample space for the entire team, with shelf and cubby space to accommodate clothing, valuables, and gear.  Clean showers are a given; I’ve seen some hellish showers in my lifetime.  Luxury amenities - steam room, workout area, sleep pods - are simply superfluous.  It’s just a place to get changed, dude.  Nothing more, nothing less.

Do I have any diabolical plans for the opposing team’s locker room?  Nope.  Kill them with kindness, that’s my motto.  They get what we get - an ample, clean facility.
