Sorry, couldn't resist... 
There was a Mumsnetter called Frangi
Whose holiday made her so angry,
But it wasn't the plumbing, the noise or the place,
It was an 8 year old girl with an angelic face.
But how, you cry now, did this child cause such stress?
Was it tantrums, or rudeness, or refusing to dress?
No my dear reader, it wasn't one simple thing,
Although her insistence on winning was enough of a sin ...
The true cause of the ire was her bedtime routine
Which really and truly was not ever seen.
She would not settle like all good children do
And actually behaved like a bit of a poo
She pranced and she danced and caused quite a big stir
And never set foot past her own bedroom door
Our poster, who needed a bit of a break,
Couldn't speak out for good friendships sake
But instead would witness (while silently seething)
A child, with no manners, her rest time stealing
But didn't her mother just send her to bed?
No my sweet reader, the mother was led
On a wild merry dance of indulgence and pleading
While all other children were peacefully sleeping.
The moral with children is that friends you may be
But spoiling the child is not good when there's three
Some lines should be drawn, and some rules put in place
So mums can get rest and wake with smiles on their face!
... 
for you Frangi ... hope it all works out
