DS turns 16 next week and wants a sleep over. Trouble is our house is all one level and quite small. If they slept in the lounge, then my DD would be up all night as her room is next to it.
DS and his mates are also very loud and 'sweaty' and one of our neighbours has previously kicked off at DS language when playing the X Box, so god knows what she'd make of a group of them at gone midnight 
I feel the garden is out for similar reasons.
Does anyone have any ideas? Some kind of experience that could involve a group of them? Perhaps with an overnight stay? A sleepover is the only bloody thing he's asked for
