Can you cite one official listening service which is offered not in an hotel or a complex but in a village which anyone can access and where there are a mixture of privately owned and holiday rental properties?
You seem determined to miss the point.
No matter where parents decide to use or mirror the listening type of childcare, or to use baby alarms when on holiday,
it ALWAYS involves making the decision to leave their sleeping children alone in their rooms. It goes without saying that in every case those parents genuinely thought it was safe to do that - in the same way as the McCanns did - otherwise they wouldn't have done it.
According to you leaving sleeping children alone is totally unacceptable behaviour full stop - and you are entitled to your opinion. However it
is only an opinion and one which quite obviously all of those parents mentioned above would not share with you - especially before Madeleine disappeared.
It seems to me that the reluctance by some to mention or even acknowledge the existence of those thousands of other parents is because it somewhat 'spoils' the concept that only the McCanns have ever committed this apparent 'crime of the century' of leaving their sleeping children alone and that it is absolute proof that they are evil uncaring selfish parents. The fact that they are only one set of parents amongst thousands who have done the same - puts rather a large spanner in those particular works IMO.
Either those parents on holiday who made the decision to leave their children alone in their rooms did so because they believed it was safe, or there are thousands upon thousands of parents out there who - because they left their children asleep and alone in their rooms - have proved they are also evil, uncaring, selfish parents. You can't have it both ways.
