Thanksgiving Cheat Sheet, Part 6: Let the Turkey Rest
Remember that the turkey can sit, cooked, under foil on the counter for 45 minutes and be perfectly fine (actually better!) than if you're rushing it to the table and cutting into it right away.
Meat that is allowed to rest is juicier, so err on the side of having the turkey done early: just tent with foil and use the oven to rewarm or keep warm the green bean casserole and mashed potatoes.
This also means you have plenty of time to get the gravy just right.
