I was in a position where it was just me at the house when the packers came. I had already done various things to be ready when they arrived on the 1st morning;
1) packed the suitcases & bags and got together everything we were taking on the plane and put it all on our bed.
2) emptied the attic
3) unplugged computers & stereo system and packed it into the original boxes we still had (but I hadn't sealed them up)
4) had a HUGE clearout of stuff (this was over a number of weeks as it was a slow process what with working fulltime, looking after DS & OH being in NZ already)
5) still had the skip on the driveway so any last minute things that needed to be ditched could be
6) packed our wine cellar stocks in special packing boxes my OH sourced
As the packing was going to take more than one day on the 2nd day I put everything that was coming with us, or being given to friends into the car before the packers arrived. This then gave the packers a 'clear run' at what was left.
During the packing I provided a supply of small ziplock bags so that as items were dismantled (our beds for example) the 'bits' could be put in a bag and taped securely to the item. I also made sure that there were enough mugs & t-spoons left out for drinks.
HTH & best of luck!
