In my opinion the cultural differences between the Portuguese and the British made it very difficult for the Portuguese to understand and accept the McCann's method of 'childcare'. It was difficult for many British people to understand too, despite what Jane Tanner said.
It is normal (culturally, traditionally, education/examples seen) [for] English tourists to leave, for some time, their small children alone in the bedroom/apartment to sleep while the parents are absent, normally guaranteeing that it is done for short periods of time (15/30 minutes). At those times there is a sporadic check, in time, of the places where the children are.

What, I wonder, did Jane mean? As far as I know the group she was with were the only people staying at the Ocean Club that week who decided to do that. That makes it anything but normal imo.
As far as YOU know !! What factually do YOU actually know about, "if others were doing something similar to the Tapas Group" ?
You know nothing about the actual figures, do you?

Seems likely that like many average families in the UK, Jane as a child, went to Butlins where half hour checks were made by complete strangers to the kids. This was just to the outside of the chalet.
and at some of the bigger sites they could be a quarter of a mile or more away.
Or her family camped or caravanned. IMO It was common when we caravanned to see other caravanners quite a distance from their own caravan leaving sleeping kids, whilst they chatted and had a drink together.
