I challenge you to demonstrate that your assumptions are facts. Where does it say that those parents reported the crimes to the Policia Judiciara? Where does it say that the McCanns received information from the first investigation which was withheld from everyone else?
You really don't know this already?
SnipPortuguese police knew about the attacks but ruled out a link to Madeleine’s disappearance because the crimes were spread over a wide geographical area and there were no apparent attempts at abduction.
Four of the burglaries were in Carvoeiro, six in the Vale da Parra, Praia da Gale district, and two in Praia da Luz.
Nine of the 12 incidents were reported to Portuguese police at the time they happened, but British investigators only became aware of three break-ins when the victims came forward in response to televised appeals last autumn.

Snip“Who’s thinking about child abductions in a sleepy, out-of-town tourist resort?” asked Gerry McCann, expressing the common view among parents that places stuffed full of other parents with small children are supremely secure.
Chillingly, the McCanns learnt after the abduction that not only are such resorts an obvious target for paedophiles, but also that parents should have been warned to be vigilant.
In 2008, when the Portuguese police officially stopped pursuing the case, their files revealed that in the three years preceding Madeleine’s disappearance, three intruders had been disturbed in children’s bedrooms within an hour’s drive of Praia de Luz and five children had been abused in their beds while on holiday in the Algarve.
Evidence had not been collected, let alone collated or publicised.
https://www.telegraph.co.uk/news/newstopics/madeleinemccann/8503610/Kate-McCann-why-didnt-they-believe-her.htmlIs that information ... or the note detailing the dining arrangements available to you or me in the files we have seen? Yet it was familiar enough to Kate McCann for her to make reference to it in MADELEINE.
I wouldn't call it speculation ... I would deduce (arrive at a fact or a conclusion by reasoning; draw as a logical conclusion) that Kate McCann had access to information unavailable to you or I.
