For family emergencies they call the house which is more effective (because it's a lot louder to wake everyone up). I do not sleep with the cell phone next to me or in the same room so draining battery overnight serves no real purpose in my case. But when I travel abroad for overnight work (rarely), it's as simple as disabling Blocking Mode.
