I think it seems you are doing too much beforehand and don't push others to do their bit.
Work - yes, it's a bit busier to ensure handover is done, I still manage to do this in my normal hours, I tell my colleagues that I need to focus on this and ask them to let me in peace for an hour or two.
Why is washing and cleaning the house so much more? I tell everyone that the last wash is on this date and if it is not in the basket or worn afterwards, tough luck. I clean as normal, the only thing left is empting all bins by DH, his job, not mine.
We have a box in the living room roughtly 2 weeks prior to departure where all non-clothing stuff is being collected, books, games, spare toileteries, medication not in daily use etc, no running around collecting from various locations when packing happens. The only things needed packing the night before are chargers and electronics. DH is in charge of packing, DD and I just dump our clothes on the bed and let him get along. Over the years DD learned to pack herself, yes, we had to buy hairbrush or a pack of knickers but she learned quick. Obviously when she was younger we went through her things together and I kept a closer look on what she wore when.
We pay for a cab instead of taking the car now to the airport, before that we paid for valet parking. Costs were part of the holiday budget and often not a lot less than the cab.
DD had always some new thing for the plane, often bought when on offer long beforehand and she was allowed one thing at the airport, often a magazine I normally refused to buy. Ipad with downloaded movies and headphones ensured she was happy and DH and I could read in peace. Again - holiday treat.
