Righto - I have took on board what you have all said and I'm going to let dd have her sleepover.
Only 3 friends and dd though, so only 4 altogether.
Younger dd's will stay at Dsisters so noise won't be a massive factor. Have told dd that I refuse to allow her to be awake all night and will be imposing bedtime at around 11pm
Oh, and no food after 8pm
Can't do swimming but would like an activity to tire them out - any ideas?
Oh yes, and the bonus is that they all have to be somewhere at 11am on Sunday, so I get rid of them early
Thanks for all your input
