I don't think it's a question of being judgemental. We can all feel compassion for that family and pray that that little girl is found safe and well, but it doesn't mean we can't or indeed shouldn't ask questions.
I don't believe everything I read/hear on the news, but reports have consistently said the apartment was about 200 yards from the restaurant. Certainly, the photos published showing both buildings would appear to bear that out.
If that is indeed the case (and apologies if it isn't), it is exactly like me tucking my children in bed, leaving the house and walking 25, 50, 100 or 200 yards down the street to have dinner with a friend, or a drink in my local.
People who have been to that same site say some of the apartments are 15 mins' walk from the restaurant, but that parents staying in even the further ones are often quite happy to leave their children and do the regular checking on them thing.
Well I'm sorry, but I do think that's irresponsible and negligent. Yes, we all take calculated risks in life, but they have to be reasonable and responsible. Some woman on breakfast TV yesterday was equating it to leaving a 12 year old at home alone. Well, it really isn't in the same league. I let my 12 year old walk to school alone and yes, it's still a risk, but it's not the same as letting my hypothetical 5 year old do the same.
But that doesn't mean I don't wish those particular parents get the news they so desperately want. I wouldn't wish this situation on anyone.
