We eat early (noon-1pm) due to family needs (and I do NOT get up at the crack of dawn!!), so I do most of the "hard work" the day before. I make one major (and a few minor) side dishes the day before -- if time does not decrease it's quality. As for everything else, do all the "sous chef" work the day before -- ALL the chopping (carrots, celery, onion, dill, parsely, etc.) and pre-measuring into separate bowls (i.e, if two dishes need onions, I have the onions chopped and measured into two separate containers in fridge.) Bascially, have all the necessarily ingredents for every single dish ready to go -- in fridge or on counter top. Have all the cooking pots & pans out and ready to go. Then all you are really doing on Thanksgiving Day is assembling and putting in the oven. This is the only way I can pull off a noon dinner. Since you're eating around dinner-time, maybe this is enough to let you out of the house in the morning!
I hope you get to the parade this year!!
