Do you think I don't know all this about rinks? I'll be blunt, if they can't take it - get out of the sport. Tennis players have to play on different surfaces including grass, clay, and hard court. Types of lighting varies, casting shadows as the sun sets, ( light varies when playing indoors vs outdoors), different temperatures and humidity from match to match vary, along with wind conditions. ALL that variation, and yet no one whines. No one.
But someone wants to cry about ice hardness and rink size?
This is a sport, not kindergarten.
