pack the kids off to someone else while you move - SOOOOOOOO much easier (and even better if you can pack them off somewhere that will deliver them to school after the first night )
Make sure you get your Royal Mail redirection sorted more than 5 working days before you moved
Use linen/clothes etc to pack the top of boxes and wrap fragile stuff in, especially if you're short on newspaper.
Get all your friends collecting newspaper NOW
Get plenty of wine in the fridge for the days before you move
Go through all your papers and make a list of all the people you need to inform of change of address (saves rushing around 2 days before your moving date thinking "shit")
If possible go and measure up the rooms in your new house before you move so you can work out where the furniture goes before it's moved in. Much easier to say "sofa over>>>>>>>>>there" "TV>>>>>>>>>>>there" as it's being taken in than trying to move it all around afterwards
LABEL your boxes clearly. Not just what's in it but the room it's from/destined for too. Means if you take your time unpacking not only will the boxes be in the right rooms but you'll know exactly what's in them too
Buy a LOT more parcel tape than you think you'll need, you'll be amazed how a few small boxes use up so much tape
Find out what time is the best time to get boxes from your local supermarket and get yourself there at that time (17 decent sized boxes in one go 2 nights ago from a trip at 11.15pm).
Rope your friends in to help you pack
Make sure you've either cleared the freezer, or have friends that stick your freezer stuff in while you're waiting for your freezer to get back down to the right temperature
BREATHHHHHHHHHHHHHHHHHHH (said to herself)
