I've only heard bad things, on the rumour-mill / friend-of-friends type. In short: Do it if you really need to, be prepared for a pretty rubbish 12 to 36 hours, and a terrible two weeks if you do test positive, or are unlucky enough to arrive from a country that is suddenly added to a quarantine blacklist, like Pakistan was whilst some residents were in the air. AFAIK there isn't any special treatment with or without kids as far as I understand.

What you have described seems to match what I had also heard, the real issue is going to be time (variable, the earlier in the morning you can arrive the better, as it seems to be sequential, but also processing those who arrived the night before. They only do tests in normal working hours I understand, and it takes approximately 3-4 hours then for the results, but with a variable number of people ahead of you in the queue). If you do pass then you can go home / go into a hotel for mandatory governenment self-quarantine, so make sure you have a way to get food/drinks delivered, or ideally have a family member prepare that for you.
