Pinstripe it's not that it takes soooo long, it's that my life is already far too manic and deep cleaning is way (way way way!) down the list of priorities! You could probably do most rooms in 1 day of that week, or maybe 2/3 evenings uninterrupted (as in, about 1-2 hours maybe twice or 3 times would do it). I just don't get that sort of time.
But it has been handy to get a general list organized, of main cleaning and seasonal maintenance items that I can tackle, and festive preparations, to get through over the course of the autumn and early winter. So that by early December, I am mostly organized, and can actually enjoy the festive season itself, have a reasonably clean and organized house, be relatively organized for Christmas and not up until 2am the night before international postage cut off dates wrapping, or 2am on Christmas Eve.
And I may even (it's happened a few times, just not every year) actually feel like and be able to host a gathering of some sort at home without blushing at the state of it, or getting frantically stressed at trying to organize it.
(DH may feel the same about me and my hoarding tendancies, as you do about your DH!).
For freezer meals, individual portions are great (I have a bunch of ceramic dishes from "Cully and Sully" ready meals). But I also do a few family sized meals - I have 4 pyrex family sized, and 3 two person sized, rectangular dishes with plastic lids. The great thing about those is that you can make a meal and freeze it, and the dishes stack when the lids are on. Once frozen, remove the meal from the dish and pack in a large freezer bag to stack/store. Just try to make sure you keep 1 dish empty (or use a meal in a dish first from the frozen ones) so then when you want to defrost the meal - you take off the wrappings and put it into the dish straight from the freezer and it will keep the shape. Then the dish can go into the oven as well.
I'm going to use the quieter days at work this month to get my lists in order, as I know this autumn is going to be worse than usual (DD starts secondary school, 3 big work projects will have busy periods between Sept and Christmas, and I am losing a Cub leader as well so will have no weekends off as we'll have no cover).
