I think I kind of got this figured out:
The plans are pretty similar- in that by the week of Christmas most cleaning, organizing, cooking will be done so we can ENJOY the holiday!
Holiday Grand Plan:
There is a cleaning area of focus each week. For Ex: Kitchen. So, you would do everything needed to clean the kitchen- top to bottom.
Then there is a check list of things to do that week for Holiday Prep.
For Ex: Make and freeze a meal you will use during the holidays. And: Buy 2 cans or something you will need during the holidays.
Houseworks Holiday Plan:
Goes with the House Works book by Cynthia Townley Ewer (CEO):
This has more specific cleaning/organization themes. For ex: Food Storage Area. Or: Wardrobe week.
So, with this one you wouldn't actually be doing the entire kitchen. You would work on the pantry, fridge, freezer.
It lists page numbers to the book that discuss that particular theme.
It also gives tasks to do that week for Holiday preperation that go with that week's theme.
For ex: During Wardrobe week, your Holiday prep would include: Check family member's holiday clothes- do they need to be dry cleaned, mended, etc. And: Make room in the coat closet for guests coats.
