(To be honest, the following was written by my husband, Rick)
For 16 years, we have held Thanksgiving at our house for the family--sometimes nearly 20 people attend this dinner held in a tiny 1,200 square foot house. In those 16 years, we have found our "home court advantage," per se. Here's the run-down:
First, we get organized and delegate all the difficult dishes to our family while we take care of all the easy stuff. If you are the one delegating, why not make your life easy? Believe me, if someone is delegating you to do something, it WON'T be easy--that's what we call, "home court advantage."
Secondly, this is all happening at your house. You REALLY should have to cook NOTHING because you have to set-up you home, pre-clean, and clean up afterward. Those are the biggest jobs of all and you don't need to also be doing all of the difficult cooking.
Fourth, delegate dishes like those mashed potatoes to some unsuspecting soul. Mashed potatoes is the most difficult of all basic Thanksgiving dishes and requires tons of prep and finesse. If you don't get all the parts right, you end up with wallpaper paste or cement.
Fifth, remember that you are in control if you are delegating. The opposite is also true, if you don't get a jump on delegating, you lose control and become the slave of your family--don't let this happen to you or YOU could be the turkey for Thanksgiving!
