Turkey Question...advice from better cooks appreciated!

[Raven]

I'm doing Thanksgiving at my Mom's place in the Boston area. I am in New Hampshire. We need to eat around 1 o'clock. I thought I would get up really early tomorrow and cook the bird unstuffed(it's only 12 pounds so it should be done by 10 am). I'll make the gravy and then put the bird and everything else in the car and go. It takes me about 2 hours to get to Boston so the bird should be cool by the time I get there. I figured I'd warm up the bird and the gravy in Mom's oven and make everything else (including the dressing) when I get there. Does that sound like a good plan? Will it hurt to reheat the turkey?
