The first house move DH1 and I did, we did all ourselves. I was the driver. We finished at 2am and had to take the hired van back to the rental place in Edinburgh with our bikes in the back so that we could cycle the five miles home afterwards. I vowed then: never again!
The next time we moved, the kids (3 and 5) and I went to stay with my mum for a few days while the removal took place. DH had instructions to get the beds ready for all of us in the new house and to have some food in. He did this.
We didn't have a car at the time so I was arriving by train with the kids.
I don't see why your DD and DGD couldn't come to you while the OH is doing the packing, galen, though maybe she doesn't trust him to do it right. Hey ho. She's making things hard for herself as well as disappointing you. 
This weather is getting me down. Is it May or March?
