This isn't on !! They are complete dicks to want to stay with you. Anyone in their right mind wouldn't even suggest this.
This is your 1st baby ? There's SO much involved when baby arrives, your baby is not going to sleep 12 hours solid. You'll feel like a feeding machine. The baby will cry , you'll cry... your body will be very sore and healing, all you'll want is your pjs. Your sleeping pattern will change. They're will be washing coming out your ears.
There's so much change, the last thing you need it's people all around your house.
You could go early you could go over, either way your body will be exhausted and you'll need to be building your energy either for the birth or dealing with a new born.
Your chances of PND will increase as you'll be trying to walk on egg shells and keep them happy.
I've had 5. On EVERY one of them I could not bare visitors for more than a hour or two.
Does your dh actually realise that with new borns you need the full run of your house. You need to be able to go to another room during the night, you can't do everything in one room. Even comforting a crying new born most end up walking room to room. What will you do ? Go out ? You don't know what kind of baby you are going to have, one of mine woke hourly, one fed every 2 hours, one thought night was day, one I had such bad pnd that I would sit and cry at nothing. One was born very ill and we ended up staying in hospital for 3 months. The list goes on. Does your dh think everything will be the same and wtf are these visitors thinking !!!!!
