I'm the exact opposite, I'll pack about an hour before I leave for the airport.
Less and less work as it gets closer? Well, I'm reading this forum when I still have 200 images to process by EOB. Which is about 20 minutes from now... :D
3 work days after today...I'm afraid they're all going to be as non productive as today has been so far. Saturday is laundry and pre pack day, work Sunday/Monday and do all the "before you leave town errands" on Tuesday along with the final packing. Drive up Wednesday and dive in.
