Resist the roasting bags. You'll end up with a slimy, mushy turkey. The Nesco, or that style roaster, has worked best for me. The oven in my apartment is okay for most things but the temperature is not accurate. Cook on low following the directions with your roaster. Baste when you need to escape the 'tives. The turkey is done when you can insert a meat thermometer into the meat reaching the required temp for your size turkey--careful not to hit a bone. I make my stuffing on the side with homemade stock. Stuffing the bird increases the baking time thereby increasing your risk of very dry white meat.
I like the traditional sides: roasted sweet potato, stuffing, green bean casserole (homemade NOT with soup mix), rolls, cranberry sauce, and some sort of pumpkin dessert. Have fun and hope the dinner goes well. Relax and keep things simple.
