SJOG Hospital Murdoch - are they strict on enforcing visiting hours?

Need to go see someone on Thomas Furlong Ward.
Trouble is between working fulltime and solo parent of 2 under 5, getting there between 3-8 is becoming near on impossible.
No, I don’t have anyone to watch the kids.
I’d like to know the possibility of going tomorrow, literally be less than 30 min visit, give some drawings kids made and gone again.
If they’d answer the phone I would ask them directly.

Advice? Ta
