Are you having professional movers ? If so, you really need to get them to pack you too - doesn't cost much extra, and is a total blessing. They label everything very clearly, and hanging clothes go in hanging boxes, clothes drawers went as the whole drawer etc.
As we have an integral garage here, we got them to put everything but kitchen contents, clothes, furniture and electricals in there. DH stood at the front door and directed each box as it came in. This meant that the house was pretty sorted almost immediatly.
Friends arrived on the Saturday - some unpacked the kitchen and others took DS off so that we could unpack.
If you have airbeds and sleeping bags, then pack them in the car so that you'd have something to sleep on even if you can't find all the beds.
Pack 3 days clothes, bedding, nappies, kettle, plates, cups, cutlery and essential food in the car so that you have them with you whatever. Also all essential document
This move, we only knew 2 weeks before that we would be moving 200 miles across the country, and it all still went well
