What to do if Turkey is done early ?

Happy Thanksgiving All ! I plan on smoking my 11 LB Turkey on my WSM 18" at 325 -350. The Turkey will be brined, so I am figuring about a 2 1/2 - 3 hr cook. If the turkey is done before, what is the best way to hold until it is time to eat? Is putting in an ice chest or an oven on low heat a good option? Or will it dry the Turkey out? I like to start smoking the Turkey a little early just to give me some extra time and my guest are not waiting on food to be cooked. Any suggestions would be helpful.

Thanks,
Ryan

I've wrapped in foil, towels and put in cooler. Holds pretty well. I wouldn't put in oven but that's me.

Ck this out. I've taken the center and lid off the base section leaving the turkey on the cooking rack and set it aside. It stayed warm a LONG time without continuing to cook (much).

That was my thought as well. Thanks for the responses guys.
