They are perfectly nice people, 4 of them, aunt of DH's ex (11 years's ex) and her house is tiny. My DH knows them well. They aren't any trouble.
But 10 days?
I'm saying I don't want to have sex while there's people I don't really know in the house. It's not that soundproof. So I reckon he needs to engineer a time for them out the house. He thinks I'm being precious.
Though there's a bit of me thinking if we had really noisy sex they might spend a bit more time out of the house.....
