We usually fly early morning and midweek so i'm always in work the day before but i do try and finish by about 4ish by going in very early. I get home and choose what clothes to take with me, iron anything that needs it and pack my case, all my suncreams and toiletries will have been bought the weekend before. The whole choosing clothes, ironing and packing I can do in about 2 hours (obviously i have a pretty good idea what i want to take, it's more about which clothes are left behind!!)
My girlfriend packs gradually over a few days so her case is largely done but we finish off both cases when she gets home. Then cats off to cat hotel, have some tea, empty the fridge, tidy the house, pack my hand luggage (mp3, tickets, passports etc) and carry cases downstairs. Check the balance on my currency card and go to sleep.
