So can I just confirm then a few points?
You say that in order for the parents to go out together they must pay for a registered and CRB checked babysitter? That no other will do?
Presumably then if someone came onto Mumsnet asking if they were being unreasonable in leaving their dd with the neighbour's teenage daughter, you would take the opportunity to tell that person that they were being selfish and irresponsible?
The nursery worker at the nursery in Peterborough who took indecent photographs of children - wasn't she CRB checked? Would that story put you off putting your kids into nursery? Or would you claim that was very very rare and a one-off?
What happened to Madeleine McCann was also very very rare and a one-off. In fact it is much rarer than CRB checked people being done for abuse. Not just sexual but physical abuse. There is another nursery in Birmingham where a male nursey worker was found guilty of abuse and also in South Lanarkshire. Very rare but it happens and it's a darn sight more common then abduction.
Those are the facts.
I won't bother to tell you how many children died whilst in house fires but based on the stats that someone kindly gave much earlier in the thread I can tell you that 1 person died in a hotel fire in 2010.
So, based on this research, I would conclude that for parents to leave a child alone in a hotel room with the kind of video monitor that I linked to for £95 or a cheaper breathing monitor (which flashes if the child's breathing changes) is therefore less of a risk. Particularly if they do this as a one-off.
It's not just to go to the bar for a few drinks. It's to get some adult time with your partner, to discuss fears and worries and just to chat. For instance dh and I would talk about the issues surrounding his family and his inheritance, how my family are being nasty to me, about our financial worries, about our lack of a sex life and what we could do about it - things that are difficult to discuss when there are distractions such as the children, having to get school things ready, packed lunches, TV etc.
A short break in a hotel is, for some, the best time to thrash out issues, get anxieties and worries off your chest and to offer support to each other. If that means leaving your child asleep in the hotel room rather than use the babysitting service of a strange member of staff, then I'm all for it. A monitor is probably better than a stranger who doesn't want to be there, watching over your child or listening outside the door (as some posters have said is the extent of hotel babysitting services).
So if some posters feel this is still not for them and they'd rather pay a professional CRB checked sitter to watch over their kids then that's fine. If others would rather not go anywhere at all without their children, well so long as you and the kids are happy then that's fair enough too.
