They will pack and move everything so fast!
Whenever I move I always do the following:
Pack all important documents and paper in my work bag and that goes in my car.
Pack bed linen, clothing, pyjamas, towels and toiletries in a suitcase so I can have them to hand for a couple of days whilst I unpack. Put it in the car.
Pack an essentials box with tea, coffee, wine, cat food, silverwear, mugs and the kettle. That goes with you on the day in your car
So all these things and the cat come with me.
I then make up the beds the minute they've put them together so we can flip after takeaway for tea.
If you can get rid of some stuff before the packers get there that would be good.
Good luck!
